Homework 1 - Suvat

Your first homework is to practise your maths skills.

All of these questions need you to use the SUVAT equations we used in class.

You must show your working (including which equations you used)

1. A train accelerates uniformly from 21m/s to 35m/s over a distance of 350m. Calculate the acceleration.
2. A car accelerates from rest with acceleration 0.8m/s² for 5 seconds.                                             Find the final velocity of the car.
3. Jamie sees a flash of lighting outside of his window, 3 seconds later he hears the bang. How far away was the lightning strike? (Hint the speed of sound is 300m/s)
4. A train starts from rest and accelerates uniformly at 1.5m/s² until it attains a speed of 30m/s. Find the time taken and the distance travelled.
5. A ball is launched straight up from the ground with a speed of 20m/s. Calculate the maximum height the ball reaches
6. The ball then falls back to the ground, what is the speed of the ball when it hits the ground?

Extension

John is 1.72m talls and shots a toy gun from head height at a speed of 15m/s, What will be the speed of the bullet when it hits the ground?
