1. Change in speed = 14 m/s; time taken = 2 seconds. Calculate the acceleration.
2. A car accelerates from rest (zero speed) up to a speed of 30 m/s in 12 seconds. Calculate the
acceleration.
3. A cyclist in the Tour de France accelerates down a hill from 22 m/s to a speed of 37 m/s. This
acceleration takes him 2 seconds. Calculate the acceleration.

2. 4. A rocket launching in the Ukraine accelerates upwards from rest to a speed of 12 km/s in 8 seconds.
Calculate the acceleration.
5. A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration ? Is this acceleration
higher than that of a car which accelerates from 0 to 30 m/s in 8 seconds?
6. A car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. Find
the car’s average acceleration.
7. A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. What is the lizard’s average acceleration?
8. If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 50 m/s2 for 3 seconds, what will
its final velocity be?

1. Olga runs at a speed of 13 m/s for a time of 120 seconds. How far does she run?

3. 2. Eloise’s Ferrari goes from 0 to 50 m/s in 3 seconds. What is its acceleration?
3. Maria F drops a small dog from a tall building. It takes 5 seconds to hit the ground and the acceleration due
to gravity is 10 m/s2. How fast was the dog moving when it hit the ground (assume no air resistance)?
4. Pierre drives his Skoda at a speed of 15 m/s and he drives a distance of 15 km. How long does the journey
take?
5. James is flying an SR-71 Blackbird at a speed of 3668 km/h. If he flies for 2 hours, how far does he fly?

4. 6. Julia’s jet-ski accelerates from 10 m/s to 25 m/s in a time of 2.5 seconds. What is its acceleration?
7. Albert and Michael drop a coin from the top of the Eiffel tower. It takes 8 seconds to hit the ground. How
high is the Eiffel tower? (Assume no air resistance)
