A particle starts from the origin at f = 0 s with a velocity of `10.0 hatj m//s` and moves in the x-y plane with a constant acceleration of `(8.0 hat + 2.0 hatj) m s^-2`.

A particle is moving with a velocity 5m/s towards east and its velocity changes to 5m/s north in 10 second. Its acceleration is

A particle is moving eastward with a velocity of 5ms^-1 in 10s, the velocity of the particle changes 5ms^-1 northward. The average acceleration is

An object dropped from a cliff falls with a constant acceleration of 10 m/s2. Find its speed 5 s after it was dropped.

A seconds pendulum is suspended from the roof of a lift. If the lift is moving up with an acceleration 9.8 m/s2 its time period is

A cyclist is with a speed of8m/s. As he approaches a circular trun on road of radius 80m, he applies break and the speed is reduced at the rate of 0.5 m/s every second. What is the magnitude and direction of net acceleration of the cyclist on the turn?

Velocity of a particle depends upon t as V = A + Bt + Ct^2 . If velocity is in m/s, the unit of A will be :

A bullet of mass 10 g travelling horizontally with a velocity of 150 m s^-1 strikes a stationary wooden block and comes to rest in 0.03 s. Calculate the distance of penetration of the bullet into the block.

Two equal drops of water are falling through air with a steady velocity of 0.1m/s. if the drops coalese, what will be its velocity?

The position of a particle is given by barr = 3.0thati + 2.0t^2hatj + 5.0hatk . Find the velocity of particle at t=2sec
