Medium
If a force of 10 N is applied on a body of mass 2 kg initially at rest, what will be its velocity after 3 seconds?
Medium
A ball is thrown vertically upward. At the highest point, which of the following is true?
Easy
Two bodies of masses 3 kg and 6 kg are moving with velocities 4 m/s and 2 m/s respectively in the same direction. What is their relative velocity?
Medium
A force of 20 N acts on a 4 kg object initially at rest for 5 seconds. What is the displacement of the object during this time?
Medium
A block is placed on a frictionless inclined plane of angle 30°. What is the acceleration of the block down the plane? (Take g = 9.8 m/s²)
Hard
A force of 50 N acts on a body of mass 10 kg. The body moves with acceleration a. If the force is doubled and mass is halved, what will be the new acceleration?
Hard
Two ice skaters push each other and move in opposite directions. If the mass of skater A is 50 kg and skater B is 70 kg, and skater A moves with 3 m/s, what is the velocity of skater B?
Hard
A force F acts on a body of mass m producing acceleration a. If the force is applied at an angle θ to the horizontal on a frictionless surface, what is the horizontal acceleration?
