G . A 6 0 - g ball of clay falls and an instant before it hits the ground it has a speed of
3.0 m/s.
a. How much work did the floor do on t he clay to bring it to a stop?
b. If the force that stopped the ball was 6 0 N, how long did it take for the ball to come to a stop?
A ball of soft clay with mass 1 kg falls from a height of 10 m starting at rest. When the clay hits the ground it flattens and comes to a stop. Which of the following is true? Gravity does work on the ball equal to 980 J, and all this energy is dissipated during the deformation of the ball on impact. Gravity does work on the ball equal to 98 J, and all of this energy is dissipated during...
in a time, t. 0 A ball of soft clay (mass, m) hits the floor with speed v and stops. Use momentum considerations to find the average force of the ball on the floor.
0 A ball of soft clay (mass, m) hits the floor with speed v and stops. Use momentum considerations to find the average force of the ball on the floor.
A 0.24 kg bouncy ball falls and bounces of the floor. The speed of the bouncy ball is 18 m/s before it hits the ground while the speed of the bouncy ball is 13.5 m/s on the rebound. It takes .02 seconds from the time the ball first touches the ground to the time when the ball first leaves the ground. What is the magnitude of the Average force on the ball?
A ball is dropped from the top of a 68 m building. How long does it take for the ball to hit the ground? In the previous problem, what is the speed of the object the instant before it hits the ground?
5. A ball is dropped from rest from the top of a building of height h 100.25 m friction, find (a) How long does it take the ball to hit the ground? (b) What speed (b) What speed does the ball travel the instant before it hits the ground?
A 170 gram ball is dropped from rest off of a cliff. the ball then drops straight down to the ground, 19m below. if the speed of the ball just before it hits the ground is 8 m/s, how much work is done to the ball by the fore of air resistance as it falls?
A ball with a mass of 2 kg falls from a height of 3 m on the ground in point B. From there the ball bounces (coefficient of restitution e = 0.8) to come to the ground a little later in point C. A 3 m B 26 o The speed (in x and y direction) of the ball just before it hits the ground in point B. U o The speed (in x and y direction) of the ball...
A bowling ball falls off the top of a building and hits the ground with a velocity of 40 m/s How high is the building? How long does it take?
A ball is launched from the top of a building 80 m high at an angle of above the horizontal with a speed of 63 in/s. How long does it take before the ball reaches its highest point? What is the maximum height of the ball above the ground? How long is the ball in the air before it hits the ground? How far does the ball travel horizontally before it hits the ground? What is the acceleration of the...
