A body of mass $2 kg$ collides with a wall with a speed of $100 ms^{- 1}$ and rebounds with the same speed. If the time of contact is $1/50 s$ , the force exerted on the wall is

Options:

Answer:

Solution:

We know that, $F = \frac{d p}{d t} = \frac{m d v}{d t} = \frac{m \times 2 v}{1/50}$ $= \frac{2 \times 2 \times 100}{1/50} = 2 \times 1 0^{4} N$
