A tennis ball of mass m(t) is held just above a basketball of mass m(b), With their centers vertically aligned, both are released from rest at the same moment, so that the bottom of the basketball falls freely through a height h and strikes the floor. Assume an elastic collision with the ground instantaneously reverses the velocity of the basketball while the tennis ball is still moving down because the balls have separated a bit while falling.
(a) The two balls meet in an elastic collision. To what height does the tennis ball rebound? (Use any variable or symbol stated above along with the following as necessary: g.)
The systems shown below are in equilibrium with m = 6.10 kg and θ = 35.0°. If the spring scales are calibrated in newtons, what do they read? Ignore the masses of the pulleys and strings and assume the pulleys and the incline are frictionless.
how come the formula: (change)v / (change)t = (change)x cannot be used for this exercise When a 58-g tennis ball is served, What is the magnitude of the net force acting on the ball
