Question

The horizontal velocity of an object is measured as 12 m/s.
There is no horizontal accelerationWhat is the horizontal velocity
of the object after it travels 10m (in m/s) ?

Answer #1

HORIZONTAL ACCELERATION GIVEN = 0

Horizontal velocity = 12m/s

If acceleration is zero in horizontal direction then there will we no change in velcoity after covering 10 m in horizontal direction beacause if you apply equation of motion

(V^2) = U^2 + 2as. In X direction

Here a = 0 therefore v= u

This is the case of projectile in which horizontal acceleration is always zero but it has vertical acceleration i.e g downwards so net velocity changes accordingly as vertical component velocity increase or decreases but no effect on horizontal velocity.

Hope you understand

an object is thrown with an initial horizontal velocity of 10
m/s and an initial velocity of 15 m/s. what is the horizontal
velocity after 2 seconds? wha tis the vertical velocity of the
object after 2 seconds?

The motion of an object along a horizontal hallway is given by
?(m) = 10m + 4 ? ? ∙ t − 2 ? ? 2 ∙ ? 2 . Determine
a. The initial position of the object;
b. The initial velocity of the object;
c. The acceleration of the object?
d. The average velocity of the object from 4 to 10 s.
e. The velocity of the object after 10s

14. An object with a
horizontal velocity of 5.6 m/s and leaves a sheer cliff
horizontally and travels in the x-direction for 122 ft before
striking the ground. How high is the cliff? Assume no air
resistance and flat horizontal ground at the bottom of the
cliff.
A) Use the conversion
factor 1.00 m = 3.28 ft to convert 122 ft to m. Keep five sig
figs
B) For how long in s
did the object travel in the x-direction...

at
time t=0 s, an object is moving on a horizontal plane with a
velocity v0x=1.5 m/s , v0y=3.5 m/s. as the object slides, a
constant acceleration acts on it that has the following components:
ax=-2.3 m/s^2 and ay=4 m/s^2 . determine the magnitude of the
displacement of the object after 2s

An object at the top of a stairwell is given a horizontal
velocity of m vx = 2.75 m/s . Given that the rise and run (height
and depth) of each step is 10cm determine which step the object
will hit first

An object is thrown from the top of a building with a
horizontal velocity of 40 m/s. The height of the building is 100 m.
Where does the object strike the ground (horizontal range)?
2.
A long jumper leaves the ground at an angle of 20⁰ above the
horizontal axis at a velocity of 11 m/s. How far does he jump in
the horizontal direction?

A 100 g object with velocity vector [1, 3] m/s collides with a
120 g object having velocity vector [-3, 2] m/s. After the
collision the 100 g object is observed to have velocity vector
[2,-1] m/s. What is the velocity vector of the 120 g object after
the impact?

1) A child pushes under an angle of 300 an object 2m
on a horizontal floor at constant speed. If the force applied by
the child is 20N what is the work done?
2) A 200kg car traveling at 5 m/s runs into the rear of a car
that has a mass of 150 kg and travels with 10m/s What is the speed
of the cars after the collision assumed perfectly inelastic?

A 4-kg projectile travels with a horizontal velocity of 600 m/s
before it explodes and breaks into two fragments A and B of mass
1.5 kg and 2.5 kg, respectively. If the fragments travel along the
parabolic trajectories shown, determine the magnitude of velocity
of each fragment just after the explosion and the horizontal
distance where segment B strikes the ground at D.

2. A 0.768 kg object is moving with a velocity of
2.53 m/s. A 0.532 kg moving object
hits it. After
collision, the 0.768 kg object has a velocity of 3.22 m/s and the
0.532 kg
object has a velocity of 0.636
m/s. What was the velocity of the 0.532 kg object
before collision? (All
motion is 1-D; friction can be ignored.)
