An object has velocity `vec v = (i+2hatj+3hatk)m//s`. A constant acceleration of the object for which its speed starts decreasing is:

A 3.00 kg object has a velocity (6.00 hati - 2.00 hatj) m//s . What is the net work done on the object if its velocity changes to (8.00 hati - 4.00 hatj) m//s ?

The initial velocity of an object is vecu = 5hati + 10hatj m//s . Its constant acceleration is veca = 2hati+ 3 hatj m//s^2 . Determine the velocity and the displacement after 5 s.

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 particle is moving with a constant acceleration veca = hati-2hatj+2hatk m//s^(2) and instantaneous velocity vecv = hati+2hatj+2hatk m//s , then rate of change of speed of particle 2 second after this instant will be :

An object has a velocity, v = (2hati + 4hatj) ms^(-1) at time t = 0s . It undergoes a constant acceleration a = (hati - 3hatj)ms^(-2) for 4s. Then (i) Find the coordinates of the object if it is at origin at t = 0 (ii) Find the magnitude of its velocity at the end of 4s.

Two objects move in the same direction in a straight line. One moves with a constant velocity v_(1) . The other starts at rest and has constant acceleration a. They collide when the second object has velocity 2v_(1) . The distance between the two objects when the second one starts moving is :-
