A body at rest is given an initial uniform acceleration of 8m/s2 for 30s after which the acceleration is reduced to 5m/s2 for the next twenty seconds. The body maintains the speed attained for 60s, after which it is brought to
a body B moving a velocity of 20m/s collid with anothet body A moving in the same direction on the same horzontal line with a velocity of 10m/s, if the of body A is three time the same of body B and the collion perfectly elastic
Two vehicles are moving at a velocity of 100km/hr and 60km/hr the magnitude along the road is 500km and the vehicle with a vehicle with a velocity of 100km/hr began the journey 2.5 hrs ealier.CALCULATE the distance the vehicle
1)A car is moving with uniform accelaration. It moves along two point A and B and enters with velocity 50 m/s and 80 m/s respectively . Find the velocity when the car is moving in b/w the point A and B. Here the body is not
A 1100-kg car moving on a horizontal surface has speed v = 60km/h when it strikes a horizontal coiled spring and is brought to rest in a distance of 3.1m .What is the spring stiffness constant of the spring?
