A golfer hit the ball at rest. such that the contact between ball and golf stick is 0.1 s . If the golf ball covers linear distance of 200 m in 2 s, calculate magnitude of force applied, assuming there is no friction and mass of golf ball is 50g.

u=0
t=0.1 s
S = 400m
time for linear distance = 2 s
m=0.05 kgDistance covered by ball in 2s = 400 mDistance covered by ball in 1 s = 400/2 = 200 mFinal velocity of ball = 200 m/sv=u + at200 = 0 + a x 0.1a = 2000 m/s2
Force
F = ma = 0.05 x 2000 = 100 N.
