3. For this series of 5 questions, a block is released from the position shown with a certain initial velocity. It then slides down the smooth (friction-less) path for which the function is given in the image. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 2) As the block slides down, its potential energy converts into kinetic energy. If its initial velocity is 1.5...

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...

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...

4) If the block has mass of 70 kg and its initial velocity is 3.4 m/s (at x = 3 m), determine the normal force N which the path exerts on the block right before it reaches the spring (at x = 0). Your answer must include 1 place after the decimal point and the proper unit. Take g = 9.81 m/s2. у v = 1 m/s y = 0.25x2 k = 5 kN/m www.land x 3 m

DYNAMICS-15 A block with a spring attached to one end slides along a rough surface with an initial velocity of 7 m/s. After it slides 4 m, it impacts a wall for 0.1 s, and then slides 10 m in the opposite direction before coming to a stop. If the block's deceleration is assumed constant and the contraction of the spring is negligible, what is the average acceleration of the block during impact with the wall? spring block +X (A)...

The 2,5-kg block A is released from rest in the position shown and slides down on a curved surface. The block then hits the 3-kg pallet B. The block and the pallet move together and come to rest after sliding a distance d across the floor. Suppose that the curved surface is rough and velocity of block A before hitting the pallet B is 5,5 m/s. Determine the impulse exerted by the pallet B on the block A during impact....

Problem 1: A block (m 7.0kg) is released from point A and it slides down the incline (0-40°) where the coefficient of kinetic friction u is 0.25. It goes 5.0 m and hits a spring with a spring constant k 500 N/m. During the compression and the reaction of the spring, we assume that the bloc is moving on a frictionless surface (u 0). a. How far is the spring compressed? b. What would be the velocity of the bloc...
