In the previous problem, if the car has a mass of 3000 kg and the angle of ramp from theground is 200, what is the tension in the cable and the force exerted by the ramp on the tire?
A particle is projected from a point a with a velocity of 21m/s at an angle of 53.1 to the horizontal. one second later another particle is projected at a point 0.3m below a with initial velocity of 31.5m/s at an angle of 36.9 to the horizontal. (i) prove that the particles collide (ii) dind the time
