A firework takes off from rest and accelerates upwards for 7 s with constant acceleration 5 m s-2, before decelerating at a constant rate of 10 m s-2 until it explodes at the highest point of its trajectory. Sketch the velocity-time graphs from the information given. Take upwards to be the positive direction.

A racing car is being tested along a straight 1 km course. It starts from rest, accelerating at a constant rate of 10 m s-2 for 5 s. It then travels at a constant speed until a time t s after it started moving. Show that the distance covered by time t is given by s=125+50(t-5). Hence, find how long it takes to complete the course.
