The driver of an 1800 {kg} car travelling on a horizontal road at 100 kmh suddenly applies the brakes. Because of a slippery pavement, the friction of the road on the tires of the car, which is what slows down the car, is 20.0 percent of the weight o..
Horse races once around a circular track in a time of 176 s, with a speed of 26 m/s. What is the radius of the track.
A spring stretches 0.150 when a 0.300 kg mass is hung from it. The spring is then stretched horizontally 0.100m from its equlibirum point and released. determine maximum acceleration of mass
At t1 = 5.00 s, the acceleration of a particle moving at constant speed in counterclockwise circular motion is a1=(2m/s^2)i + (9m/s^2)j At t2 = 6.00 s (less than one period later), the acceleration is a2= (9m/s^2)i - (2m/s^2)j The period is more t..
A fisherman standing on the edge of a pier hooks a fish on the surface of the water, and reels in the fishing line at a constant 0.50m/s. If the fisherman's fishing rod is a height of 3.0 m above the water, at what speed is the fish moving (horizonta..
