Question

Two football players have a head-on collision and grab onto each other’s uniforms. The 50 kg Wyatt was moving at 4 m/s, while the 30 kg Kenny was moving in the opposite direction at 2.5 m/s. What is their final velocity after impact? Round to the nearest hundredth.

Answer 2

1.56 m/s

Explanation:

There will be momentum conservation,

i.e, initial. momentum will be equal equal to final momentum

initial momentum

=50kg×4m/s -30kg×2.5 m/s

=200-75 kg m/s

= 125

now they both grab each others mean they will be treated as single body after collision

let their final veloocity be z then,

i.e, final momentum = 80kg × z m/s

now, momentum conservation

125 =80z

i.e, z=25/16 ≈1.56

i.e, their final velocity will be 1.56 m/s
