    Football question (kinematics)

    If this is a one-dimensional free-fall problem , then this is how you solve it: Your Δx is 6 Final velocity is given to you: Since it says maximum height, at that height your final velocity will be 0. Most importantly, your acceleration will be -9.8 m/s^2 since once the football is in the...

    A simple car and friction problem

    Hi! I cannot answer this question: The force that accelerates a car along a flat road is the frictional force exerted by the road on the car's tires. Explain why the acceleration can be greater when the wheels do not spin. I know that friction is the force that is moving it forward and...
