- A 1000-kg car moving at 10 m/s takes a turn around a circle with a radius of 50.0 m. Determine the acceleration and the net force acting upon the car.A ball of mass m is suspended on a light string of length l from the ceiling. The ball is then put into motion such that it rotates in a horizontal circle with a rotation rate of w ( rad/s). Notice that the string makes an angle of with respect to the vertical during this motion. 1) find the tension in the string and the angle. 2) if the ball moved at twice it's first rotation rate, find the new angle the string would make with respect to the vertical. c) find the tension in the string at this new rotation rate. 6) how much faster is the ball speed with this new rotation rate as compared to the oroginal speed? Find a ration of the two speed.5) A pilot of mass 65 kg in a jet aircraft makes a complete vertical circle in mid-air. The vertical circle has a radius of 1.70 km at a constant speed of 215 m/s.
