A body falling from rest describes distances S₁, S₂ and S₃ in the first, second and third seconds of its fall.  The ratio of S₁ : S₂ : S₃ is 

A car moves a distance of 200 m.  It covers the first-half of the distance at speed v. The  average speed is 48 km/h. Find the value of v. 

A car is moving along a straight road with a uniform acceleration.  It passes through two points P and Q separated by a distance with velocity 30 km/h and 40 km/h respectively.  The velocity of the car midway between P and Q is

If the water falls from a dam into a turbine wheel 19.6 m below, then the velocity of water at the turbine is ( Take g = 9.8 m/s²)

A car travels for half of its time at 80 km/h and for the rest half time at 40 km/h.  Total distance covered is 60 km.  What is the average speed of the car?

One train A 120 m long is moving in a direction with a speed of 20 m/s. Another train B 130 m long is moving with a speed of 30 m/s in the opposite direction.  The train B crosses the train A in a time

The ratios of the distance covered by a freely falling particle, starting from rest in the first, second, third ... nth seconds of its motion

A ball P is dropped vertically and another ball Q is thrown horizontally from the same height and at the same time.  If air resistance is neglected, then, 

A body dropped from top of a tower fall through 40 m during the last two seconds of its fall.  The  height of tower is (g = 10m/s²)

A stone released with zero velocity from the top of a tower, reaches the ground in 4 s.  The height of the tower is ( g = 10m/s²)
