As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction u, = 0.730. Find h such that the block's speed after crossing the rough patch is 3.70 m/s. rough patch 15.0 cm

Two blocks are free to slide along the frictionless wooden track as shown in the figure. The block of mass m1 = 5 kg is released from rest from the position shown, at height h = 5.00 meters above the flat part of the track. At the bottom of the track rests mass m2 = 10 kg. No work is done by non-conservative forces a.What is the speed of block m1 just as it reaches but before it collides with block m2 (use Cons. Of Energy)? b.What is the velocity of m1 just after it collides elastically with m2 (use Conservation of Momentum)? and what is the velocity of m2 just after it collides elastically with m1 (use Conservation of Momentum)? c.

A 1.4 kg mass slides to the right on the surface having a coefficient of kinetic friction 0.25. The object of the speed of v(initial)=2.7 m/s when it makes contact with a light spring that has a force constant of 50 N/m. The object comes to rest after the spring has been compressed a distance d. The object is then forced toward the left by the spring and continues to move in that direction beyond the spring's unstretched position. Finally, the object comes to rest at distance D to the left of the unstretched spring. Find the distance of compression d. Find the speed v at the unstretched position when the object is moving to the left. Find the distance D where the object comes to rest.
A Block-Spring System A block of mass 1.0 kg is attached to a horizontal spring that has a force constant of 2,000 N/m as shown figure (a). The spring is compressed 3.0 cm and is then released from rest as in figure (b). (a) A block attached to a spring is pushed inward from an initial position x-O by an external agent. (b) At position x, the block is released from rest and the spring pushes it to the right. (For the following, when entering a mathematical expression, do not substitute numerical values; use variables only.) (a) Calculate the speed of the block as it passes through the equilibrium position x - 0 if the surface is frictionless. SOLUTION Conceptualize This situation has been discussed before, and it is easy to visualize the block being pushed to the right by the spring and moving with some speed at x = 0. Categorize We identify the system as the block and model the block as --Select- system. Analyze In this situation, the block starts with v, - 0 at x, = -3.0 cm, and we…
O Macmillan Learning A ball of unknown mass m is tossed straight up with initial speed v. At the moment it is released, the ball is a height h 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 is the mass of the ball, m, assuming that there is no friction or air resistance? Using g to represent the acceleration due to gravity, enter an expression for m in terms of g, h, d, k, and v. m = ||N|- =-= kxx ² gh kg m V h th kogum
