In order to obey a speed restriction, the brakes of the car are applied for 3 s, reducing the car’s speed from 30 m s−1 to 17 m s−1. The brakes are then released and the car continues at a constant speed of 17 m s−1 for a further 4 s.

The total momentum in any closed system will remain constant. When two or more objects collide, the collision does not change the total momentum of the two objects. Whatever momentum is lost by one object in the collision is gained by the other. The total momentum of the system is conserved. Newton’s Cradle!!

Mechanics 2.10. Particles on a slope (with Friction) mc-web-mech2-10-2009 Here, as in leaﬂet 2.7, particles on a slope are considered, but this time including friction. WorkedExample1. If a particle, of mass M kg, is on the point of slipping down a rough plane that is inclined at an angle θ to the horizontal, what is the coeﬃcient of friction?

In Fig. 3, two particles, each with mass m=0.85 kg, are fastened to each other, and to a rotation axis at O , by two thin rods, each with length d=5.6 cm and mass M=1.2 kg. The combination rotates around the rotation axis with angular speed = 0.30 rad/s. 3 5. The diagram shows a plank AB, of mass 15 kg and length 2·8 m, being held in equilibrium with AB horizontal by means of two vertical ropes, one attached to the end A and the other attached to the end B. A man of mass 80 kg stands on the plank at point C, where AC = 0·9 m. Solutions 2.4-Page 140 Problem 3 A mass of 3 kg is attached to the end of a spring that is stretched 20 cm by a force of 15N.
