1 1. The following two blocks are pulled along a smooth frictionless surface. Find the tension in the rope between two blocks. 55 N 12 kg 21 kg15. A Porsche travelling at a constant velocity of 32 m/s passes a Mini parked on the side of the road. When the Porsche is 50 m ahead, the Mini starts accelerating uniformly at 3.5 m/s2. How fast is the Mini travelling when it reaches the Porsche ?.15. A Porsche travelling at a constant velocity of 32 m/s passes a Mini parked on the side of the road. When the Porsche is 50 m ahead, the Mini starts accelerating uniformly at 3.5 m/s2. How fast is the Mini travelling when it reaches the Porsche ?.16. Three vectors are given by A = 3i, B = -li +1j and C = 4j. Find the magnitude of the resultant vector.18.A 25 kg hanging object is connected by a light, inextensible cord over a light, frictionless pulley to a 3.2 kg block that is sliding on a flat table. Assuming a smooth frictionless surface of a flat table find the tension in the string. (assume: g = 9.81 m/s?).19. An object moving in a straight line has the displacement-time graph shown. Find the average velocity for the trip. s [m] 25 - 6 9 12 t [s]
