Problem 1: A rock of mass m = 0.79 kg is attached to a massless string of length L = 0.84 m. The rock is swung in a vertical circle faster and faster up to a speed of v = 4.3 m/s, at which time the string breaks. This occurs when the string is horizontal as shown in the figure.

Question

Please answer Question 1

Problem 1: A rock of mass m = 0.79 kg is attached to a massless string of length L = 0.84 m. The rock is swung in a vertical circle faster and faster up to a speed of v = 4.3 m/s, at which time the string breaks. This occurs when the string is horizontal as shown in the figure. Break Part (a) What is the magnitude of the tension, in newtons, at which the string breaks? Numeric : A numeric value is expected and not an expression. Tf = Part (b) How high, in meters, does the rock travel? Use a value of h = 0 at the location of the break. Numeric : A numeric value is expected and not an expression. h =
