Question

A ball of mass 60g is dropped from a height of 3.4m it lands on top and the surface is not frictionless (Kinetic friction is 0.3). The hight of the ramp is 1.8m and the ramp is tilted at an angle of 20 degrees.

a) What is the velocity of the ball at the top of the ramp

b) At the bottom of the ramp it collides with and sticks to a ball of mass 73g. What is the velocity after collision?

c) They are stuck together when the ball collides with a spring of spring constant 300N/m. How much will they compress it?

d) Then they go up the ramp. How high will they go?

Answer #1

Two balls are placed, one above the other, and dropped from a
height of 1.05 m. The bottom ball has a mass which is 6 times the
mass of the top ball. They are dropped from rest. When the balls
strike the floor, they have a head on, elastic collision with one
another. (Assume that the bottom ball strikes the floor, instantly
reverses direction, and then collides with the top ball, which is
still travelling downward.) How high will the...

Two balls, of masses MA= 40g and MB= 60g are suspended. The
lighter ball is pulled away to a 66 degree angle with the vertical
and released. The two balls stick and move together (collision is
completely inelastic). (length of suspension is 30cm)
1. What is the velocity of the lighter ball just before
impact?
2. What is the velocity of the combined mass after the
collison?
3. What will be the maximum angle reached by the combined mass
(theta...

A block with a mass m1=2.3kg is sliding along a frictionless
surface with a velocity of 7.3m/s. It collides inelastically with
mass m2=1.7kg and the two blocks stick together. They then slide
down a frictionless incline with a Height 95cm. How fast are they
going when they reach the bottom of the incline?
Part B. If the coefficient of kinetic friction, uk is 0.15 along
the surface at the bottom of the ramp. What distance will the
blocks side before...

A ball of 2 kg travels in the x direction with a velocity of 4
m/s. It collides with a ball of mass 3 kg which is initially at
rest. After the collision, the first ball travels at a velocity of
2.5 m/s at an angle of 30 degrees from the x axis. What is the
velocity of the second ball? NOTE: what if they stuck together?
What kind of collision would that be?

block 1 of mass m1 slides from rest along a
frictionless ramp from an unknown height h and then
collides with stationary block 2, which has mass m2 =
3m1 . The collision is an elastic one. After the
collision, block 2 slides into a friction-filled region where the
coefficient of kinetic friction is 0.5 and comes to a stop through
a distance d = 10 m in that region. What is the height
h?

An object with a mass m = 3.5 kg is released from rest at the
top of the ramp. The length of the ramp is 4 m. The object slides
down the ramp reaching a speed of 1.8 m/s at the bottom.
(a) How much time (in sec) does it take the object to reach the
bottom of the ramp? (use kinematics equations)
(b) What is the acceleration of the object (in m/s2 )? (use
kinematics equations)
(c) If the...

An object of mass m1 approaches with velocity v1 another object
of mass m2, which is at rest, next to a spring having force
constant k. The spring is fixed to a wall and m2 can compress the
spring. This is one-dim horizontal collision without friction. We
consider two collision scenarios, one which is perfectly inelastic,
and the other which is elastic. (a) In the first collision case the
object m1 strikes m2 and sticks. Moving together, they compress the...

A 100.0 g ball is launched from the top of a building. The ball
is launched from rest by a constant force that is applied,
resulting in the ball going from 0 m/s to 75 m/s over a distance of
60 cm. When the ball flies off the top of the building it has an
initial velocity of 120.0 m/s @ 33.0o above the
horizontal. Sitting on the ground is a tube, with a diameter
slightly larger than the ball....

A
ball is dropped from rest from the top of a 6.10 m-y’all building,
falls straight downward, collides inelasrically with the ground,
and bounces back. The call loses 10.0% of its kinetic energy every
time it collides with the ground. How many bounces can the ball
make and still reach a windowsill that is 2.44 m above the
ground?

A ball is thrown horizontally from the top of a 68 m building
and lands 110 m from the base of the building. Ignore air
resistance.
a. What is the vertical component of the velocity just before
the ball hits the ground?
c. What is the angle of the ball just before it hits the ground
( in degrees below x-axsis)?
