Question

Please explain with working
During a paintball fight, a paint pellet of mass 150g hits a stationary target with a speed 220m/s . It takes 0.025s from the moment the pellet comes into contact with the wall until it flattens onto the wall. What is the force exerted as a result of the paintball 'splat'? *
1.3 x 10^3 N
33 N
1.3 x 10^6 N
33 x 10^3 N

Answer 2

Answer:

The force exerted is $1.3*10^3N$

Explanation:

Mass of the paint pellet=150 g =0.15 kg

The initial velocity with which it hots the target is $u=220m/s$,

The time taken from the moment the pellet comes into contact with the wall until it flattens , $t=0.025s$.

Final velocity $v=0$

The acceleration with which the the paint ball comes is $a=\frac{v-u}{t}=\frac{0-220}{0.025}=8800 m/s^2$.

Hence the force exerted as a result of paint ball 'splat ', $F=ma = 0.15*8800=1320N$≈$1.3*10^3 N$
