Aplace-kicker must kick a football from a point 36.0 m (about 40 yards) from the goal. half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. when kicked, the ball leaves the ground with a speed of 22.2 m/s at an angle of 51.0° to the horizontal.?

a).The ball fall by d=8.75m height  

b). The ball is falling at time t=1.63s

Explanation:

The problem have no question to answer however typical questions are:

a).By how much does the ball  clear or fall short of clearing the crossbar?

b) Does the ball approach the crossbar while still rising or while  falling?

,, ,.

The time to get the distance

a).

Now find the ball's height at this time

b).

Now find the reach maximum height if the football reaches is is maximum height

Solve to t

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
