Question 626412: From a car moving a 36 kmhr-1, a ball is thrown at night angle to the motion of the car and with a speed of 6 ms-1. What is the speed of the ball (relative to the Earth) at the beginning of its flight? Answer by Emsley(35) (Show Source):
You can put this solution on YOUR website! Adding the two velocities as vectors the resultant velocity is the hypotenuse of a right angled triangle with sides 36 and 6. That is root(36^2+6^2)
