Each of the sliders A and B has a mass of 1.8 kg and moves with negligible friction in its respective guide, with y being in the vertical direction. A 11-N horizontal force is applied to the midpoint of the connecting link of negligible mass, and the assembly is released from rest with e = 0. Calculate the speed v with which A strikes the horizontal guide when e = 90°. 0.18 me 11 N 0.18 m, X-

4. The 0.5-kg collar C starts from rest at A and slides with negligible friction on the fixed rod in the vertical plane. Determine the velocity v with which the collar strikes end B when acted upon by the 5 N force, which is constant in direction. Neglect the small dimensions of the collar. A 200 mm. 30⁰ 5 N B

Q17. As shown in the image below, the 0.7-kg ball strikes the rough ground and rebounds. The directions of its velocities before and after the strike are shown. If the speeds are v₁ = 27 m/s and v₂ = 12 m/s, determine the magnitude of the impulse (in N.s) the ground exerts on the ball. Assume that the ball does not slip when it strikes the ground, and neglect the size of the ball and the impulse produced by the weight of the ball. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. V₁ Your Answer: 45° Answer 30° 02

The 1-1b ball A is thrown so that when it strikes the 10-1b block B it is traveling horizontally at v = 30 ft/s as shown in (Figure 1). Figure A B 1 of 1 Part A If the coefficient of restitution between A and B is e = 0.6, and the coefficent of kinetic friction between the plane and the block is μ = 0.4, determine the distance block B slides on the plane before stopping.
