- (Questions 16-18) A 25 kg box is at the bottom of a frictionless incline that is 7 m long as shown and makes an angle of 20 degrees with the horizontal. A person applies a constant horizontal (NOT parallel to the incline, but horizontal) force to the box, starting from rest. It reaches the top of the ramp in 13 seconds. 16. Draw a free-body diagram of this situation showing all forces on the box. 17. What was the magnitude of the box's acceleration during this process? 18. What was the magnitude of the force applied by the person?Two blocks are joined by an inextensible cable as shown. If the system is released from rest, determine the velocity of block A after it has moved 2 m. Assume that the coefficient of kinetic friction between block A and the plane is 0.25 and that the pulley is weightdess and frictionless. 200 kg ㄱ 300 kg A BCould someone explain for me? Thank you in advance!

- Draw diagram or sketch to help you understand the situation. A 73kg runner starts walking at 3.4 m/s [E] and begins to speed up for 6.0 s, reaching a final velocity of 11.2 m/s [E]. Calculate the net force acting on the runner.A person throws a 2.50 lb stone into the air with an initial upward speed of 15.0 ft/s . Part B Make a free-body diagram of the forces for this stone at its highest point.(Draw the force vectors with their tails at the origin of the coordinate system.) Part C Make a free-body diagram of the forces for this stone when it is traveling downward. (Draw the force vectors with their tails at the dot.)A skater of mass m standing on ice throws a stone of mass M with speed v in a horizontal direction. Find the distance over which the skater will move in the opposite direction if the coefficient of kinetic friction between the skater and the ice is ?k .
