A 50 g rubber ball is hit by a racket. Ball´s velocity before the hit is v → i = - 20 · i → - 20 j → m / s ,after the hit, the velocity is v → f = 15 · i → + 20 j → m / s . Determine the impulse exerted by the racket on the ball and the value of the force, assumed constant, if the are in contact for 0.05 s. Solution. WitrynaOverview of Newton'S Second Law. An object in motion is said to be moving and this state is represented by a quantity called velocity. Velocity is a vector quantity that represents the speed and direction of an object. Any push or pull movement on the object is referred to as force. According to Newton’s first law of motion, a significant ... corporate treasury funds
