Question JO1 ball of unknown mass m is tossed straight up with initial speed v. At the moment it is released, the ball is a heighth above a spring-mounted platform, as shown in the figure. The ball rises, peaks, and falls back toward the platform, ultimately compressing the spring a maximum distance d from its relaxed position. Assume that the spring is perfectly ideal, with spring constant k, and that the mass of the spring and platform is negligible. What...

1. (30 points) A 2-kg block A is pushed up against a spring compressing it a distance r-0.1 m (i.e., the spring is unattached to the block). The block is then released from rest and slides down the 20° incline u it strikes a 1-kg sphere B that is suspended from a 1-m inextensible rope. The spring constant 800 N/m, the coefficient of friction between A and the ground i length of the spring d-1.5, and the coefficient of restitution...

5) If the block has mass of 40 kg and its initial velocity is 3.4 m/s (at x = 3 m), determine the maximum compression of the spring (after the block has pushed in the spring and come to a stop). The spring constant is given in the image. Your answer must include 3 places after the decimal point and the proper unit. Take g = 9.81 m/s2. v = 1 m/s y = 0.25x k = 5 kN/m www.nl...
