3. A 10 kg block A is released from rest 2 m above the 5 kg plate P, which can slide freely along the smooth vertical guides BC and DE. The coefficient of restitution between the block and the plate is e 0.75. Determine the veloc 2 ity of the block and the plate just after impact. What is impact? The spring has an unstretched length of 600 m450 mm Ans: A 2.61 m/s, p 7.31 m/s and d 0.32...
Block A (M = 10 kg) is released from rest and slides down an initially frictionless ramp (θ= 30°, L = 10 m). It then passes over a rough patch of ground (µk= 0.633 and d = 5m) before impacting block B. Block B (m = 20 kg) is initially at rest and suspended by a rigid bar of negligible mass and length R = 5m. The coefficient of restitution during the impact is e = 0.75. Determine the maximum...
Block A (M = 10 kg) is released from rest and slides down an initially frictionless ramp (@= 30%, L = 10 m). It then passes over a rough patch of ground (W=0.633 and d = 5m) before impacting block B. Block B (m = 20 kg) is initially at rest and suspended by a rigid bar of negligible mass and length R = 5m. The coefficient of restitution during the impact is e=0.75. Determine the maximum deflection angle reached...
The 1.5 kg ball A is released from rest from a height. As it descend hits a solid wall. If the coefficient of restitution is 0.85 determine : rebound height after the impact and angular velocity for a 30° angle respect the release position (the horizontal) Wall
A block of mass M = 4.000 kg is released from rest at the top of an incline of angle θ = 24.0º w.r.t. the horizontal. The coefficient of kinetic friction between the block and the incline is µk = 0.200 and the length of the incline (hypothenuse of the triangle shown below) is L = 6.00 m. ( w.r.t. = with respect to) I am trying to find: a. The work done by the normal force for the complete...
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...
A 3 kg block (block A) is released from rest at the top of a 20 m long frictionless ramp that is 4 m high. At the same time, an identical block (block B) is released next to the ramp so that it drops straight down the same 4 m. Find the values for each of the following for the blocks just before they reach ground level. (a) gravitational potential energy Block A ? Block B ? (B) kinetic...
A small block of mass m, is released from rest at the top of a curve-shaped, frictionless wedge which sits on a frictionless horizontal surface as shown. The height of the wedge is h = 5 m. When the block leaves the wedge its velocity relative to the ground is measured to be 4.00 m/s to the right as shown in the figure. If the mass of the block is doubled to become 2m, what will be its speed when...
