A 1500 kg drawbridge, 5.66 m long, is being lifted by a cable attached to its end. The cable exerts a 10800 N force at a 50.0 degree angle. What is the net torque on the drawbridge?

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
