2. Cart 1 of mass m = 0.50kg fastened to a spring of spring constant k = 14N/m is pushed 15 mm in from its equilibrium position and held in place by a ratchet (Fig. 2). An identical cart 2 is launched at a speed of 0.10m/s toward cart 1. The carts collide elastically releasing the ratchet and setting cart 1 in motion. After the collision, cart 2 is immediately removed from the track. a What is the maximum compression of the spring? b How many seconds elapse between the instant the carts collide and the instant the spring reaches maximum compression? _JM www cart 1 cart 1 Figure 2 cart 2
A block weighing 1 kg resting on a frictionless horizontal surface is attached to a spring with a spring constant of 900 N / m. The 5 kg bullet, traveling at 400 m / s, pierces the block as shown in the figure. If the block slides 5 cm towards the handle with impact, what is the speed of the bullet leaving the block and the energy loss in the collision?

5. A cart with m= 3.40kg rides on the track shown. The track is frictionless except for a level section 0.40m long where μk = 0.54. The cart is initially at rest against spring 1 (k₁ = 1400N/m) which is compressed by 8.00cm. When released it travels along the track until it reaches spring 2 (k2= 800N/m) which it compresses until the cart stops. If h₁ = 0.38m and h₂ = 0.14m, determine the speed of the cart at points A, B, C and D. Also how much will spring 2 be compressed at the end. framm] =3.40kg kží = 800 N/m Remb A k₁=1 2₁-1400/m h₁-0,38 D B d=0.40m = 0,54 мк of ....... oservation Im h₂= = 0,14
