Note that gravity also acts … WebAcceleration of an object depends on two things, force and mass. This shows that the bowling experiences a much greater force. But because of the big mass, it resists acceleration more. Even though a bowling ball may experience 100 times the force of a tennis ball, it has 100 times the mass.
Web8. A force acts on a car of mass m so that the speed v of the car increases with position x as v = k x 2, where k is constant and all quantities are in SI units. Find the force acting on the car as a function of position. 9. A body of mass m moves in a horizontal direction such that at time t its position is given by x (t) = a t 4 + b t 3 + c t, where a, b, and c are constants.
