1.A cargo truck having a weight of 4000 lb skids through a distance of 46 m before colliding with a parked Toyota land cruiser having a wight of 2000 lb. After collision both vehicles skid through a distance equal to 10 m before stopping. If the coefficient of friction between tires and pavement is 0.6 m, compute the speed of the truck after collision.
2. A driver of the service car at Solair Casino Hotel is traveling at 55 mph on a wet road. An object is spotted on the road 450 ft. ahead and the driver is able to come to a stop just before hitting the object. Assuming standard perception/reaction time of 2.5 sec and practical stopping distance, determine the grade of the road if the car has a deceleration of 11.2 ft/sec2.
A BUS IS HAVING A SPEED OF 140 km/hr, IN A PERIOD OF 6 SECONDS, THE BUS DECREASED ITS SPEED TO 100 km/hr. CALCULATE THE RATE OF DECELLERATION.
You are coasting on your 10-kg bicycle at 15 m/s and a 8.0-g bug splatters on your helmet. The bug was initially moving at 4.0 m/s in the same direction as you. If your mass is 70 kg, (a) what is the initial momentum of you plus your bicycle? (b) What is the initial momentum of the bug? (c)What is your change in velocity due to the collision with the bug? (d) What would the change in velocity have been if the bug were traveling in the opposite direction?

The pavement is hot, so the girl borrows a skateboard for her dog and gives him a push to get him across the road so that his feet won’t burn. If the road is 10 meters wide, using the EQUATION OF WORK AND ENERGY, find the magnitude of the initial velocity required so that the dog will coast across the road and come to rest at 10 meters away on the other side of the road. The coefficient of kinetic friction between the wheels and the pavement is 0.3.arrow_forward) A 5-gal, cylindrical open container with a bottom area of 120 in²is filled with water and rests on the floor of an elevator.
