Question

A batsman hits back a ball straight in the
direction of the bowler without changing its
initial speed of 12 ms. If the mass of the ball
is .15 kg, determine the impulse imparted to the
ball. (Assume linear motion of the ball.)

Answer 1

Answer:

Explanation:

Here, u=12ms−1,υ=−12ms−1 ,

m=0.5kg , Impulse = ?

As Impulse = Change in linear momentum ∴ Impulse =m(υ−u)=0.15(−12−12)

=−3.6Ns

Negative sigh shown that impulse is along negative x - axis , i.e., from the batsman to the bowler.
