7. In a given vacuum without gravity a ping-pong ball was travelling at a straight path to the East at a speed of 20 cm/sec. A force producing a velocity of 30 cm/sec to the North hit the ball that changed its velocity and direction. a. Find its new velocity. * 30 cm/sec V 20 cm/sec O v = 30.5 cm / sec O v = 36.05 cm / sec V = 32.5 cm / sec V = 33.5 cm / sec O V = 35.5 cm / sec
