Mass of the ball =250kg
Velocity of the ball, u = 15ms-1
v = 0
t = 0.1 seconds
We know
v = u+ at
0 = 15 + a × 0.1
-15 = 0.1a
a = -1.5 ms-2
Force = mass× acceleration
Force = 250 × (-1.5)
Force = -375
Negative sign shows that force was applied in opposite direction to which the ball was travelling.
Therefire force applied = 375 N
