A hockey player receives a corner shot at a speed of `15m//s` at an angle of `30^(@)` with the y-axis and then shoots the ball along the x-axis with a speed of `30m//s` If the mass of the ball is `100gm` and it remains in contact with the hockey stick for `0.01s`, the force imparted to the ball in the x-direction is :

A

281.25 N

B

187.5 N

C

562.5 N

D

375 N

Text Solution

Verified by Experts

The correct Answer is:
D
`F_(x) = (Delta P_(x))/(Delta T) = (0.1[V_(fx) - V_(ix)])/(Delta t) = (0.1[30 + 15 cos 60^(@)])/(0.01) = 375 N`
