Question

A toy car, with mass m = 200 g is given a velocity of 10 m s at the top of the first hill with height h = 1 m. The toy car goes down the hill to the ground and starts up the second hill of height h = 2 m. At the top of the hill is a spring, with spring constant k = 100 N C . How far does the spring compress when the car gets to the top of the hill?

Four asteroids, of mass M = 3 × 106 kg, are positioned at the corners of an imaginary square of side length s = 2.4 × 108 m. Two other asteroids of mass m = 2 × 106 kg are positioned in the middle of the left and right sides of the square. If a spaceship is positioned at the middle of the bottom side of the square what is the net force on the ship in Newtons?

Answer #1

Note : Mass of spaceship is not given in the question therefore you can't find the numerical value of the force acting on the spaceship.

In my calculations i have written the expression for the net force. Put the mass respective values and get the numerical answer.

Thankyou

1. You shoot a bullet of mass m=0.025 kg into a wood box of mass
M=1.7 kg which initially is at rest. After the impact, the wood
with embedded bullet moves to the flat top of the hill, and it
continues its motion on the top. Initial speed of the bullet before
collision is vo=560 m/s. The height of the hill is h=0.3 m. The
surface has no friction. At what speed the wooden block moves on
the top of...

A bike with a mass of 24 kg is moving at a speed of 5 m/s at the
top of a semi-circular hill which has a radius of 10 meters. What
is the amount of normal force acting on the car in Newtons?

A small sports car and a pickup truck start coasting down a 12 m
hill together, side by side. The mass of the sports car is 640 kg
and the mass of the pickup truck is 1280 kg (twice the mass of the
sports car). Assuming no friction or air resistance, what is the
kinetic energy of each vehicle at the bottom of the hill? Give your
answers in joules. HINT: How does the kinetic energy of a vehicle
at...

3a. With a BALL of mass 10 kg you compress a SPRING of k = 1.00
x 106 kg s-2 by Dx = 10 cm. How HIGH does the BALL fly upward when
you release it? B. A person of mass 60 kg jumps from a height of 3
m. She lands on her feet but her knee joints each compress by 0.5
cm. What force did she put on her knees?

The figure below shows a mass m1=5.2 kg moving with velocity
v1=47.6 m/s which collides with a mass m2=3.8 kg which is initially
at rest. The collision is completely inelastic and the masses slide
up a frictionless hill of mass of height h=11.1 m. What is the
kinetic energy K of the masses when they reach the top of the
hill.
K=727 J
K=3879 J
K=2425 J
K=2061 J
K=1576 J

The figure below shows a mass m1=5.1 kg moving with
velocity v1=41.6 m/s which collides with a mass
m2=2.6 kg which is initially at rest. The collision is
completely inelastic and the masses slide up a frictionless hill of
mass of height h=9.8 m. What is the kinetic energy K of the masses
when they reach the top of the hill.
K=655 J
K=3493 J
K=1419 J
K=2183 J
K=1856 J

1) A car with a mass of 2000 kg with an initial
velocity of 10 m/s crashes into a wall. The time variation (Delta
t) is 0.015 seconds. What is the change in momentum? What is the
car's impulse and force? What if the car crashes into a haystack
with a time variation (Delta t) of 0.15 seconds. What would then be
its change in momentum, impulse and force. How about its final
velocity?

A car of mass of 1350 kg travelling at 35.0 m/s along a
highway runs out of gas and starts to coast at the bottom of a hill
15.0m high. The length of the road is 540.0 m and the force of
friction on the car is 750.0 N will the car make it to the top of
the hill?
I) if so, what will it’s speed be at that point?
II) if not, how much energy would it need...

(a) How high a hill can a car coast up (engine disengaged) if
friction is negligible and its initial speed is 106 km/h? 44.18
Correct: Your answer is correct. m
(b) If, in actuality, a 750 kg car with an initial speed of 106
km/h is observed to coast up a hill to a height 20.0 m above its
starting point, how much thermal energy was generated by friction?
177.87 Incorrect: Your answer is incorrect. J
(c) What is the...

A child’s toy consists of a m = 36 g monkey
suspended from a spring of negligible mass and spring constant
k. When the toy monkey is first hung on the spring and the
system reaches equilibrium, the spring has stretched a distance of
x = 17.7 cm, as shown in the diagram. This toy is
so adorable you pull the monkey down an additional d =
4.6 cm from equilibrium and release it from rest, and
smile with delight...
