How far underside a cyclist travel in 2.5h along strong-arm road if her average velocity is 18km/h?(45km) 2. A automobile accele lay outs along a straight road from rest to 75km/h in 5.0s. What is the magnitude of its average acceleration?(4.2ms-2) 3. An automobile is tooth root to the right along a straight highway, which we choose to be the positive x axis. Then the driver puts on the brakes. If the theatre velocity (when the driver hits the brakes) is [pic], and it takes 5.0s to slow down to [pic], what was the cars average acceleration?(-2.0ms-2) 4. Suppose you want to design an air-bag table that can cheer the driver in a frontlet collision at a speed of 100km/h. Estimate how crank the air bag must inflate to effectively protect the driver.

If the force is doubled and the cud is reduced by half, resulting acceleration is? (4a) 6. A 10kg mass and a 2.0kg mass atomic number 18 connected by a light string all over a massless, frictionless pulley. If g =9.8ms-2, what is the acceleration of the system when released?(9.

8ms-2) 7. A girl is victimization a cockroach to pull a box that weighs 300N across a level surface with continual velocity. The rope makes an weighting down of 300 above the level and the tension in the rope is 1 00N. What is the normal force of the repo! rt on the box?(50N) 8. A rifle with a weight of 30N fires a 5.0g bullet with a speed of 300ms-1. a) Find the rebound speed of the rifle.(0.49ms-1) b) If a 700N reality holds the rifle firmly against his shoulder, start out the recoil speed of cosmos and rifle.(2.0x10-2ms-1) 9. A rocket with mass of 60 000kg is placed on a launching program vertically. Its engine is started and the rocket gives out gas at rate of 50kgs-1 with a...If you want to get a full essay, order it on our website: BestEssayCheap.com
