Easy
Which of the following is Newton's First Law of Motion?
Easy
A body of mass 5 kg is moving with a velocity of 2 m/s. What is the momentum of the body?
Easy
If a force of 10 N acts on a body of mass 2 kg, what is the acceleration produced?
Medium
Two bodies of masses m and 2m are moving with velocities v and 2v respectively. What is the ratio of their momenta?
Medium
A force F acts on a body of mass m producing an acceleration a. If the force is doubled and mass is halved, what will be the new acceleration?
Medium
A car of mass 1000 kg moving at 20 m/s applies brakes and comes to rest in 10 seconds. What is the magnitude of the braking force?
Easy
An object is thrown vertically upwards with velocity u. Neglecting air resistance, what is the net force acting on the object at the highest point?
Hard
Two ice skaters push each other on frictionless ice. Skater A has mass 50 kg and skater B has mass 70 kg. If skater A moves backward with velocity 3 m/s, what is the velocity of skater B?
Medium
A body of mass m is moving with velocity v. It experiences a constant force F opposite to its motion. What is the time taken to stop the body?
Easy
A block of mass 10 kg is placed on a frictionless surface. A force F = 20 N is applied to it for 5 seconds. What is the impulse imparted to the block?
