Goku's birthplace (in Dragon Ball Z universe) is planet Vegeta which has a really high surface gravity, that is why he can jump really high on Earth because the gravity on the said planet is really wimpy and cannot hold him down. Up to what height can Goku jump on planet Vegeta if he can jump on earth up to a height of 3098.88m and the planet Vegeta has 448.90% stronger gravity? Assume that Goku launched himself on the same initial velocity for both planets. What is his weight on planet Vegeta if his mass is 98.16kg? 3.

Can someone help me understand this problem? I got an answer of 7.13 seconds but that appears to be inaccurate. It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 70 mph? Suppose that μs=1.00μs=1.00 and μk=0.80μk=0.80. Thank you for your help!
The car manufacturer wants to see how the mass of the car affects the force required to accelerate the car by the same amount. A second set of trials are run in order to see how much force is needed to accelerate cars of different masses.
