A car is moving at constant velocity on a level road. The driver now heads up a ramp to a bridge. If the frictional force remains the same and the car continues at the same constant velocity, is the engine producing more forward force than before, less than before, or the same amount? Use force diagrams to explain your answer.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
