Derive the second equation of motion, s = ut + ½ at 2 numerically? 6. Calculate the acceleration and distance of the body moving with 5m/s2 which comes to rest after traveling for 6sec? 7. A body is dropped from a height of 320m. The acceleration due to the gravity is 10m/s2? (a)How long does it take to reach the ground? (b) What is the velocity with which it will strike the ground? 8. Derive third equation of motion v2 -u2 = 2as numerically? 9. A body is moving with a velocity of 12m/s and it comes to rest in 18m, what was the acceleration? 10. A body starts from rest and moves with a uniform acceleration of 4m/s2 until it travels a distance of 800m, find the fi
