1)Will drops a ball on Connor’s foot. How long does the ball take to fall 1m? 2m? Why is the second answer not simply twice the first? 2)Ed flies to Belgium. His aeroplane has a maximum acceleration on the ground of 3.4ms-2. What is the minimum length of runway needed to reach its take off speed of 110ms-1 and how long will this take?

4)Charlie likes baseball. A baseball pitcher can release a ball at 40ms-1 after accelerating through a distance of 2.5m. Calculate the average acceleration of the ball.

5)Henry has a good

chance of surviving a car crash with a seatbelt on if her deceleration does not exceed 30g (30x9.81ms-2). Calculate the distance by which the front end of the car must collapse in if a crash occurs at 70mph.
