Hey I'm really stuck on these two physics questions, please Help!?
A car accelerates from 13.2 m/s to 19.1 m/s in 5.2 s. How many metres did it travel in this time - assuming constant acceleration?

A train of mass 55,200 kg is travelling along a straight track at 24.4 m/s. Suddenly the engineer sees a truck stalled on the track 300.3 m ahead. The maximum possible braking acceleration of the train is 1.68 m/s2. After the brakes are applied, how far short of the truck does the train stop (in meters)?
