1. If a car is moving at a given speed up a ramp at a given angle, how do I find the measurement of the arc of the parabola in which the car creates upon taking flight into the air. Also given that we know the mass of the car aswell. 2. Simple. Why does kinetic energy leave a ball when I throw it? Also is the rate in which an object looses kinetic energy the same universally?Also would the mass of the object play a role in the loosing of energy? Thank you so much you guys!
