Let the distance from the intersection, when the driver sees the red light be L, let his rection time be t_{0}. Let the initial speed of the car be v_{0}. If the driver decides to put on the brakes the moment he sees the red light, the action still takes time t_{0}, and in that time the car has...

Let the initial velocity of bullet be v_{0}. If the mass of the bullet be denoted by m, then as per the given data the mass of the pendulum bob is \frac{m}{5}. Applying linear momentum conservation along the initial direction of motion of the bullet, mv_{0}=\frac{6m}{5} v where v is the final...

Firstly the dimensions of the ramp give the angle of inclination of the ramp. If the height is \var H and the length of the ramp be \var L, then tan\vartheta=\frac{\var H}{\var L} The particle model can be used here. Let the mass of the particle be \var m Then observing the equilibrium...
