Question

if a truck crushes a person even at the lowest speed of 5 m/s. What is the reason, Mass or velocity?

Answer 1

Mass

Becoz force depends on MASS not VELOCITY

Answer 2

So, if you double the speed of a truck, you increase its force of impact four times. ... When two vehicles moving at the same rate of speed are involved in a collision, the vehicle that weighs less will take the greater impact; the larger and heavier the vehicle, the

greater the energy and momentum.which means velocity.
