Q3: The 20-kg block A shown in figure (3) slides on the surface for which Hk = 0.2. The block has a velocity v = 12 m/s when it is s = 3.5 m from the 12-kg block B. If the unstretched spring has a stiffness k = 950 N/m, determine the maximum compression of the spring due to the collision. Take e = 0.5. 12 m/ sec - 950 N/m Figure (3)
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
Box A is traveling down the smooth incline (0= 17°) and it hits box B, initially at rest, with the velocity of 5 m. Immediately after impact, box A moves up the incline with the velocity of 1 m. Determine the velocity of box B (in m) immediately after impact. Consider ma = 3 kg and mB = 18 kg. The positive direction is shown on the figure. VA В
The 50-kg block at A is mounted on rollers so that it moves along the fixed horizontal rail with negligible friction under the action of the constant 300-N force in the cable. The block is released from rest at A, with the spring to which it is attached extended an initial amount x1 = 0.233 m. The spring has a stiffness k = 80 N/m. Calculate the velocity v of the block as it reaches position B.
The 25-lb block has an initial speed of v0 = 10 ft/s when it is midway between springs A and B. After striking spring B, it rebounds and slides across the horizontal plane toward spring A, etc.(Figure 1) If the coefficient of kinetic friction between the plane and the block is μk = 0.4, determine the total distance traveled by the block before it comes to rest
Two carts are positioned on an air track. Cart A has a mass m and has a spring on one end. Cart B has a mass 2m and is at rest. Cart A moves toward cart B at a speed +v until the two carts have an elastic collision. Which one of the following statements concerning this situation is true? After the collision, both cars are moving in the positive direction. The total kinetic energy after the collision is equal to m². Car B will be at rest after the collision.
