If you push a 50 kg mass with a force of 80 N, what will be the objects
acceleration?

acceleration=1.6m/s²

Explanation:

F=m×g

g=F/m

g=80N/50=1.6m/s²

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

it is called kinetic energy
