Three weights are hung from a meterstick, which has a mass of grams, as shown in the diagram to the right. The end of the incline is slowly lifted until the crate begins to slide down the incline at a constant speed. A rocket, which has a mass of 38, kg is initially sitting at rest on the surface of the planet Venus. What will be the acceleration of the cart as it moves down the incline? How much work will be done by the applied force in pushing the mass to the top of the incline?

With what minimum speed would you have to run in order to catch up with the train? An object, which has a mass of 6. What will be the average speed of this car during these 6. What is the torque supplied by the gram mass about the What will be the linear displacement of a point on the outer edge of this disc during the 8. The time from the release of the ball until its return to the ground is measured to be 5. What will be the direction and magnitude of the torque exerted on the lamp by the applied force F about a center of rotation located at the bottom right corner of the lamp?

What will be the magnitude of the force F required to accelerate m2 to the right at 3.
