Question

Main batsman deflects a ball by an angle of 60 with changes without changing its initial speed of 20 MS management what is the impulse imparted to the ball is it mass is 0.30 kg

Answer 1

Answer:

3J

Explanation:

=2mucos60°

=2×0.15×20×1/2

=3.00J

Answer 2

Answer:6 Kg m/s (or) 6J

Explanation:

Formula = 2mucosA

Here m = 0.30 kg

u = 20m/s

A =60°

=2mucos60°

=2×0.30×20×0.5

= 6J (or) 6 Kg m/s
