Question Three a. Give the three equations of linear motion (3 marks) b. Given that the velocity of a particle is V = m+nt² where m= 10cm s ¹ and n = 2cms-1 i. Find the change in velocity of the particle in the time internal between t2 = 2s and t2 = 5s.(3marks) ii. iii. Find the average acceleration in this time interval. Find the instantaneous acceleration at time t1=2s (2 marks) (2 marks) c. A car starts from rest and accelerates at 10m/s² in 20 seconds. Find the final velocity of this car (3 marks) d. A boy rolls a ball along a flat straight platform. The ball possesses an initial velocity of 2ms when the boy releases it and it shown down with a constant negative 2. acceleration of -2m s-². How far does the ball roll before stopping, and how long does it take to stop? (4 marks) e. The mass of the moon is about one eighty-first, and its radius one fourth, that of the earth. What is the acceleration due to gravity on the surface of the moon? (3 marks) Question Three a. Give the three equations of linear motion (3 marks) b.
