Projectile Motion – Fired at ground level

A football is kicked with an initial velocity of 25 m/s at an angle of 45-degrees with the horizontal. Determine the time of flight, the horizontal displacement, and the peak height of the football .....

Projectile Motion – Pool ball leaves the table with initial horizontal velocity

A pool ball leaves a 0.20-meter high table with an initial horizontal velocity of 2.4 m/s. Predict the time required for the pool ball to fall to the ground and the horizontal distance between the tab...

Force on a batted ball – Impulse

A baseball (m = 0.14 kg) thrown by a pitcher reaches a bat with a velocity of 32.0 m/s in a horizontal direction.
a) Computer the impulse that must be applied to the ball if it is to leave the...
