A 0.3 kg ball falls down and hits the floor with a speed of 15 m/s....
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 falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that mall 0.390 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? (b) If the ball is in contact with the floor for 0.0400 seconds, what is the average force (in N) the floor exerts on the ball?
A ball of mass 0.165 kg moving with speed of 2.37 m/s hits a wall and bounces back with the same speed in the opposite direction. What is the change in the ball's kinetic energy?
ortad? (b) If the cally onto a floor, hitting with a speed of 24 m/s. It rebounds with an initial speed of 9.8 m/s. (a) What impulse acts on the ball during the contact? (b) i ball is in contact with the floor for 0.0357 s, what is the magnitude of the average force on the floor from the ball? (a) Number 22 72 Units Tkg-m/s or Ns (b) Number 636.4
A ball of mass 0.180 kg moving with speed 1.87 m/s hits a wall and bounces back with speed 1.00 m/s in the opposite direction. What is the change in the ball’s kinetic energy?
A ball of mass 0.10 kg moving with speed 2.0 m/s hits a wall and bounces back with speed 1.0 m/s in the opposite direction. What is the change in the ball’s kinetic energy?
A ball of mass 0.170 kg moving with speed 2.22 m/s hits a wall and bounces back with speed 1.00 m/s in the opposite direction. What is the change in the ball’s kinetic energy? Answer ___J
A 299-g steel ball is dropped straight down on to a hard, horizontal floor and bounces straight up. Its speed just before impact with the floor is 14.3 m/s and just after impact with the floor is 10.8 m/s. Determine the magnitude of the impulse delivered to the floor by the steel ball in LaTeX: N\cdot sN ⋅ s. Leave your answer to two decimal places, and do not include the units because Canvas does not allow units in the...
J, A falling 0.1 kg ball has a speed of 7.0 m/s just before it hits the floor and an upward speed of 5 0 ms immediately after it rebounds. The ball is in contact with the floor for 0.01 s. What is the magnitude (in N) of the average force exerted by the floor on the ball?
A 1.2 kg ball drops vertically onto a floor from a height of 32 m, and rebounds with an initial speed of 10 m/s. (a) What impulse acts on the ball during the contact? (b) If the ball is in contact with the floor for 0.020 s, what is the magnitude of the average force on the floor from by the ball? Neglect air resistance.
