- A small car and a semi-truck have the same total mechanical energy. Which of the following CANNOT be true? Question 3 options: The car must be moving faster than the truck and the truck and car are at the same height. The car is going the same speed as the truck and the truck and car are at the same height. The car is going the same speed as the truck and the car is at a higher elevation than the truck. The car is at a higher elevation and both the car and the truck are stationary.arrow_forwardA crate is given a push across a horizontal surface. The crate has a mass m, the push gives it an initial speed of 3.60 m/s, and the coefficient of kinetic friction between the crate and the surface is 0.130. (a) Use energy considerations to find the distance (in m) the crate moves before it stops. ____m (b) What If? Determine the stopping distance (in m) for the crate if its initial speed is doubled to 7.20m/s. ____marrow_forward"20 kg bear slides, from rest, 8 m down a Lodgepole Pine tree, moving with a speed of 5.6 m/s just before hitting the ground.

- A 700 kg dragster accelerates from rest to a final speed of 120 m/s in 400 m (about a quarter of a mile) and encounters an average frictional force of 1200 N.

As the block slides through distance d = 0.31 m along the ramp, its kinetic energy increases by 60 J. How much greater would its kinetic energy have been if the rope had not been attached to the block? ---Select--- F.

- Two identical test cars are driving down a test track and hit their brakes at the same position. One car istravelling at twice the speed as the other. (a) Compare the kinetic energies of the two cars.

The car is rolling down a steep hill. When the car is 12.5 m above the ground its velocity is 3.11 m/s. Assuming we can ignore friction, use energy principles to determine the initial gravitational potential energy (EGi).arrow_forwardWhen a roller coaster is at the top of a steep hill, its potential energy is maximum. When it hurdles down the slope and comes to the bottom, the potential energy reduces greatly. Hence we can say that the law of conservation of energy is not valid here since energy is destroyed. a) True b) Falsearrow_forward

In marrow_forwardAssume that before the accident happened, the car was going at a constant velocity of 60Km/h on a level highway for a distance of 10.0km. The car accelerated briefly to 70.0Km/h to pass another car and then returns to 60.0Km/h as it descends the other side of the hill, even though the driver has taken her foot off the accelerator. Describe the energy transformations taking place when the engine was not doing the work.arrow_forwardA 3500 lb SUV is traveling at 30 mph up a 6% slope when the engine quits.
