Class: XI, 11, First Year
Unit :03 Dynamics
Numeicals Covered:
3.1 A 50 N force applied on a box of mass 8.16 kg to move on the right across a horizontal surface. What is the acceleration of produced in the box.
3.2 A hockey puck with a mass of 0.2 kg is sliding on the ice at a velocity of 10 m/s. It collides with a wall and bounces back with a velocity of -8 m/s. The collision lasts for 0.1 seconds. Calculate the impulse experienced by the hockey puck and the change in its momentum.
3.3 Two objects, A and B, are initially at rest on a frictionless surface. Object A has a mass of 0.5 kg, and object B has a mass of 0.8 kg. Object A collides with object B. After the collision, object A moves to the right at a velocity of 4 m/s, and object B moves to the left at a velocity of 2 m/s. a) Calculate the total momentum before the collision. b) Calculate the total momentum after the collision. c) Calculate the kinetic energy before and after the collision.
