At the bottom of the block's path, the normal force the track exerts on the block has magnitude 3.70 N Part A What is the magnitude of the normal force that the track exerts on the block when it is at the top of its path?
1. A 20,000 pound truck is parked on a 15° slope. Find the force required to keep the truck from rolling down the hill (that is, find the magnitude of the vector component of the weight of the truck that is parallel to the slope). 2.Determine the vector v with magnitude of 30 that makes an angle of 120° with the positive xaxis. State the vector in either ordered set or unit vector notation with components written as exact values (simplified radical form).
A 48 kg ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.5 turns each second. The distance from one hand to the other is 1.50 mm. Biometric measurements indicate that each hand typically makes up about 1.25 %% of body weight Part A What horizontal force must her wrist exert on her hand? Express your answer in newtons. Part B Express the force in part (a) as a multiple of the weight of her hand. Express your answer numerically as a multiple of w (weight of her hand).
