- Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.arrow_forwardA block is being pulled along a horizontal surface by a force of 30 N at an angle of 25 degrees above the horizontal. The surface is sticky and hence a friction force of 10 N opposes the motion. What is the acceleration of the block if the mass of the block is 5 kg? What is the magnitude of the normal force?arrow_forwardYou bring a bathroom scale onto an elevator and press "up". Your mass is 65 kg. If the bathroom scale reads 750 N, (a) what is the acceleration of the elevator? You then press down and the acceleration downward is of the same magnitude. (b) While accelerating downward, you hold a small mass of 100 g attached to a string. What is the tension in the string? This elevator is in the new BU Data Science building where g = 10 m/s². Your work should include free body diagramsarrow_forward
