I asked the question here before but the solution was wrong. that's why I will ask again.  Sam and William are playing with a ball. Sam throws the ball 30 s after William started to run away from the starting position. If William is accelerating 1.6 m/s2 starting from rest, find the initial velocity of the ball to hit the moving target and the ground at the same time. The ball is thrown 1.5 m from the ground and 46° from the horizontal.   Choices: a. 112 m/s  b. 126 m/s  c. 163 m/s  d. 143 m/s

Sam and William are playing with a ball. Sam throws the ball 30 s after William started to run away from the starting position.

If William is accelerating 1.6 m/s2 starting from rest, find the initial velocity of the ball to hit the moving target and the ground at the same time. The ball is thrown 1.5 m from the ground and 46° from the horizontal.

 

Choices:

a. 112 m/s 

b. 126 m/s 

c. 163 m/s 

d. 143 m/s
