A wrecking ball used to knock down buildings has a mass of m = 1460 kg and is suspended from a cable of length L = 24 m. It reaches a maximum speed of v = 14 m/s while traveling in a circular arc toward the building. What is the minimum tension in N that the cable must be able to support without breaking? Assume the cable is massless.If the cable can only support a tension of 10,000 N what is the highest mass the ball can have in kg?
A 750 g ball swings in a vertical circle at the end of a 1.5 m long string. When the ball is at the bottom of the circle, the tension in the string is 40 N. What is the speed of the ball at that point?
Chad gets on a roller coaster. Chad and the cart rolls down the frictionless loop with a constant speed of 7.4 m/s. The mass of Chad and the cart is 0.75 kg and the radius of the loop is 0.86 m. Since the cart has a smaller dimension than the loop, the cart can be viewed as a point particle. What is the normal force at the top and bottom points? The magnitude of the gravitational acceleration is 9.8 m/s^2. Draw a free body diagram.

A block of mass m = 0.50 kg is pressed against the spring and compresses it a distance d , as in Figure P7.76. The block (initially at rest) is then released and travels toward a circular loop-the-loop of radius R = 1.5 m. The entire track and the loop-the-loop are frictionless, except for the section of track between points A and B Given that the coefficient of kinetic friction between the block and the track along AB is μk 5 0.30, and that the length of AB is 2.5 m, determine the minimum compression d of the spring that enables the block to just make it through the loop-the-loop at point C. Hint: The force exerted by the track on the block will be zero if the block barely makes it through the loop-the-loop.arrow_forward
