A light, rigid rod is 50.2 cm long. Its top end is pivoted on a frictionless horizontal axle. The rod hangs straight down at rest with a small, massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. What minimum speed at the bottom is required to make the ball go over the top of the circle? m/s
Two people swing jump ropes, as shown in the diagram. The highest point of the middle of each rope is M = 77 inches above the ground, and the lowest point is m 7 inches. The rope makes 4 revolutions per second. Write a model for the height h (in inches) of a rope as a function of the time t (in seconds) given that the rope is at its lowest point when t = 0. i ↑ h = h(t) = M Kit m -
A physics student, in a stationary elevator, places a 240.0 g mass on an electronic balance. The student hits the elevator button and it begins to move upwards. While the elevator is moving, the student records this information Time = 0 to 3.0 sec the balance reads 278 grams Time = 3.0 - 12 sec the balance reads 240. grams Time = 12.0 to 15.0 sec the balance reads 192 gram How far up (in meters) did the elevator travel? Consider: UP to be (+), DOWN to be (-) and g =9.8 m/s2 .
