A particle is dropped vertically from rest, from a height. Find the time taken by
it to fall through successive distances of 1m each.

Two atomic clocks are synchronized while on Earth before one is launched (within a GPS satellite) into a medium-altitude Earth orbit. The satellite orbits the Earth at an altitude of 22,000 km, with an orbital velocity of 15,000 km/hr. After 1000 orbits, estimate the time difference between the two atomic clocks? (Assume that only special relativity effects are present.)

light down the changes you would observe if speed of light is 1m/s and the changes if you move with half the speed of light

A car moves 30m north and then 40m east then what is the magnitude of displacement of the car?

If there is no friction between a block of mass 70 kg and the surface, what is the acceleration of block 1, a?. Enter your answer in m/s2

A lift whose floor to ceiling distane is 2.50m starts ascending with a constant accleration of 1.25m/s . Obe secind after the start , a bolt begins to fall frim the ceiling of the lift . The time which the bolt hits the floor is (take g =10m/s).

For a huge luxury liner to move with constant velocity, its engines need to supply a forward thrust of 7.70x10^5 N. What is the magnitude of the resistive force exerted by the water on the cruise ship?

an object is dropped from the window of an apartment in a high rise building reaches the ground in 3 seconds. on which floor the apartment is located if height of each floor is 4 m and window is 1 meter above the ground of that floor?

A car traveling at 30 m/s on level ground runs off a cliff. It strikes the water below in 4.0 s. Determine the point where the car hits the water (include both horizontal and vertical displacements).

A rifle is aimed directly at the centre of a target having a radius of 50 cm which is positioned at the same height as the rifle and is 200 m away. If the bullet leaves the muzzle at 500 m/s, will it miss the target? If so, by how much?
