Question

A 3 kg ball strikes a heavy rigid wall with a speed of 10 m/
s at an angle of 60º. It gets reflected with the same speed and
angle as shown here. If the ball is in contact with the wall for
0.20s, what is the average force exerted on the ball by the wall?
(a) 150 N
(b) Zero
(c) 150 √3N
(d) 300 N

Answer 1

(d) 300 N

Explanation:

here is your answer...

hope it will help you......

Answer 2

the right and is c 150√3N because A change of momentum perpendicular to the wall
