If the acceleration of an object is negative then
the object is gaining speed.
the object is losing speed.
the object is at rest.
the object cannot stop.
When an object gets negatively charged by the process of friction, then:
(a) the object loses some electrons (b) the object loses some protons
(c) the object gains some electrons (d) the object gains some protons
An object of mass 3kg is at rest. If a force →F=(6t2ˆi+4tˆj)N is applied on the object, then the velocity of the object at t=3s is :
An object travels with a speed 126km/h is bought to rest after travelling 80m. Find the acceleration and the time taken to stop the object.
An object is moving with constant speed. A force acted on the object and the object stopped.
An object accelerates from rest to 26m/s. Assuming the acceleration to be constant, find the average speed of the object.
