Initially, the system of objects shown is held motionless. The pulley and all surfaces and wheels are frictionless. Let the force F→ be zero and assume that m1 can move only vertically. At the instant after the system of objects is released, find (a) the tension T in the string, (b) the acceleration of m2, (c) the acceleration of M, and (d) the acceleration of m1. (Note: The pulley accelerates along with the cart.)
Hi! Please ndicate the given, diagram, FBD, and the solution with no shortcuts, Thanks! 5) A body system has three forces which are all at rest and in equilibrium. F1 is measured at 170 N whilst F3 is equal to340 N. The direction of each force is shown in the figure below. To balance the force within the body system, computefor the magnitude of F2 and its direction.
Nikola Jokic is running at 8.5 m/s directly toward the basket when he jumps into the air to dunk the ball. He is only able to maintain a constant horizontal jumping velocity of 85% of his running velocity during the entire flight phase of the jump. (a) What does his vertical takeoff velocity in m/s have to be when he first leaves the ground so that his center of mass is able to achieve a maximal vertical displacement of 0.7 meters during the jump? (b) How far from the basket (measured in the horizontal direction) in meters must he start his jump so that he reaches his maximum vertical jump displacement at the same time that he reaches the basket?
Blocks of mass m1 and m2 are connected by a light string over a pulley, as shown. A) Find an expression for the acceleration of block m2 if the pulley is massless and frictionless, and the surface is frictionless. B) repeat part a for the case where the surface has coefficient of friction µ and the pulley is a frictionless disk with mass M and radius R.
2. To promote their new album, BTS decided to launch a satellite into orbit that will intercept all airwaves and play their songs worldwide. To do this, he needs to mount a 200 [kg] satellite onto a 850 [kg] rocket. It blasts off vertically from a launch pad with a constant net upward acceleration of 3.80 [m/s2]. When it has reached a height of 680 [m], the satellite was released, and the rocket blew up shortly after, due to a system failure. Assume that the satellite was not damaged after the explosion. (a) What is the maximum height that the satellite will reach above the launch pad? (b) How much time will elapse after system failure before the satellite comes crashing down the launch pad?(c) How fast will the satellite be moving just before it crashes?
