QUESTION 1:

are fired from the ground with identical initial speeds, but with 0A

larger than OB . (a) Which cannonball reaches a higher elevation? (b)

One car travels due east at 40 km/h, and a second car travels north at 40 km/ h. Are their velocities equal? Explain. Two cannonballs, A and B, are fired from the ground with identical initial speeds, but with 0A larger than OB . (a) Which cannonball reaches a higher elevation? (b) Which stays longer in the air? (c) Which travels farther?. If the acceleration of an object is zero, are no forces acting on it? Explain. The force of gravity on a 2-kg rock is twice as great as that on a 1-kg rock. Why then doesn't the heavier rock fall faster
