Asoccer ball is kicked horizontally off a 22.0-meter high hill and lands a distance of 35.0 meters from the edge of the hill. determine the initial horizontal velocity of the soccer ball.

u x = 16.04 m/s

Explanation:

given,

height of the hill = 22 m

the soccer ball lands at = 35 m

initial horizontal velocity = ?

using equation of motion

t = 2.12 s

35 = 2.12 u

u x = 16.04 m/s

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
