Answer 1

Answer #1

Here ,

mass of ball , m = 2.92 Kg

initial speed , u = 10 m/s

final speed , v = 10 m/s

average force = change in momentum /time

average force = 2.92 * (2 * 10 * sin(60))/.184

average force = 274.9 N

the average force is 274.9 N

the direction of force is in -ve x - direction
