Question

A cricketer catches a ball if mass 150g in o.1s moving with speed 20m/s then he experiences force of

Answer 1

MASS=0.15 kg
speed=20m/s
Force=?

$f = \frac{m(v - u)}{t}$
$f = \frac{150(0 - 20) \times 10}{1000 \times 1}$
$f = \frac{3000}{1000}$
F=3N

Answer 2

Answer:

Force, F = 3 N

Explanation:

Given;-

          Mass, m = 150 g

                          = 0.15 kg

          Speed, v = 20 m/s

             Time, t = 0.1 seconds

Then;-

∵              F = P/t [where, f = force, p= momentum, t= time]

∴              F = mv/t   [since, p = mv]

                F = 0.15 kg × 20 / 0.1

                F = 3 / 0.1

                F = 30 N

Hence, the cricketer experiences a force of 30 N.
