Question

Which will cause more damage, a truck weighing 700 kg traveling at a speed of 17 m/s or a truck weighing 300 kg traveling at a speed of 28 m/s?

Answer 1

`700`kg, `17`m/s

Explanation:

`p=mv`
momentum = mass x velocity

`700`kg`*17`m/s`= 11900`kg m/s

`300`kg`*28`m/s`= 8400`kg m/s

the truck with more momentum is likely to cause more damage, in a collision or crash with a vehicle or other object.

the `700`kg truck travelling at a speed of `17`m/s has more momentum, so would cause more damage.
