A Ball Is Dropped 1 M To The Floor

B calculate its velocity just after it leaves the floor on its way back up.

A ball is dropped 1 m to the floor.

A steel ball is dropped onto a hard floor from a height of 1 50 m and rebounds to a height of 1 45 m. A rubber ball with a mass 0 20 kg is dropped vertically from a height of 1 5 m above the floor. A 0 5 kg ball is dropped from rest at a point 1 20 m above the floor. B suppose the ball is in contact with the floor for 0 05 s.

Assume that 40 of the mechanical energy lost goes as thermal energy into the ball. A 4 28 n s upward b 4 28 n s downward c 8 56 n s upward d 8 56 n s downward. After a 0 300 kg rubber ball is dropped from a height of 1 75 m it bounces off a concrete floor and rebounds to a height of 1 50 m. Heat capacity of the ball is 800 j k 1.

Assuming that 2 0 of mechanical energy is lost in the form of thermal energy. After the collision it rises upto a height of 1 m. The ball rebounds straight upward to a height of 0 7 m. Calculate the average force the floor exerts on the ball.

A ball is dropped on a floor from a height of 2 0 m. A calculate its velocity just before it strikes the floor. After the collision it rises up to a height of 1 5 m. The ball bounces off of the floor and during the bounce 0 60 j of energy is dissipated.

If the specific heat capacity of the ball is 8 0 0 j k then the rise in temperature of the ball during collision is take g 1 0 m s 2. A determine the magnitude and direction of the impulse delivered to the ball by the floor. A ball is dropped on the floor from a height of 10 m rebounds to a height of 2 5 m. Calculate the rise in the temperature of the ball in the collision.
