part 1 of 1 8 points A car is moving at 17 m/s along a curve on a horizontal plane with radius of curvature 46 m. The acceleration of gravity is 9.8. What is the required minimum coefficient of static friction between the road and the car's tires to keep the car from skidding? Question 13 part 1 of 1 8 points A 36 g ball is fastened to one end of a string 79 cm long and the other...
2. A ball tied to the end of a string 65 cm in length swings in a vertical circle under the influence of gravity. When the string makes an angle of thetha=25 degrees with the vertical, the ball has a speed of 2.0 m/s. a. Find the magnitude and the direction of the total acceleration when thetha=25 degrees.
Please draw the free form diagram and forces if necessary and answer ALL parts A ball of mass Mis attached to one end of a light string of length L. The other end of the string is held fixed and the ball is set in motion in a vertical circle with the string taught. If the ball moves with a constant speed V, find the tension of the string when (a) the string is horizontal (b) the string is vertical...
A steel ball of mass 0.440 kg is fastened to a cord that is 38.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure. At the bottom of its path, the ball strikes a 4.40 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block, both just after...
