A BALL IS TRHOWN UP STRAIGHT WITH A SPEED OF 10 M/S. WHEN THE VELOCITY WILL BE 0

he kicked it 10 feet straight up into the air? i think this works.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
