In the figure, three masses are attached by cords that loop over frictionless pulleys. Block B lies on a frictionless table. mA = 5.4 kg, mB = 6.2 kg, and mc = 10.7 kg. Find the tension in the cord to the right (between masses B and C) once the blocks have been released and are free to move. Your answer should be in N: Question Help: Read B

A student wants to angle a ramp such that if she releases a 2.8kg cart at the top of a ramp, the cart will travel 210cm and hit the end of the ramp in 1.6s. Neglect backwards friction and drag. What does the magnitude of the net force on the cart need to be? What does the magnitude of the cart's acceleration need to be? At what incline angle (0) does the ramp need to be slanted? m/s2 What will be the maximum speed of the cart? m/s cannot be detem check answers

A pendulum is 0.890 m long, and the bob has a mass of 1.00 kg. At the bottom of its swing, the bob’s speed is 1.60 m/s. a. What is the tension in the string at the bottom of the swing? answer in N b. The tension is greater than the weight of the bob because of which of the following? its horizontal component is increasing from zero. the bob has zero acceleration. the bob has a downward acceleration, so the net Fy must be downward. the bob has an upward acceleration, so the net Fy must be upward.

At Ted's request, Bill pushes the pizza box across the granite countertop towards Ted. When the box leaves Bill's hand it is sliding at 2.60 m/s. The box comes to rest over a distance of 110 cm. What is the coefficient of kinetic friction, uk, between the pizza box and the countertop? (Ignore air drag.)
