(a) What is the acceleration experienced by passengers on this ride in m/s2? In g’s? (b) If a certain passenger has a mass of 65 kg, what is the force in newtons that acts on him during the launch phase of this ride? What is the force in pounds?1. A 17.43kg object speeds up from 14.86m/s to 48.05m/s over a distance of 100.90m. What is the acceleration of the object? If the frictional force is 17.99N, what is the net acceleration acting on the object? 2. 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?
