Definition

C. At Highest Point: velocity points to right and acceleration points downwards

Term

A ball is thrown into the air with an initial velocity of 10 m/s at an angle of 45 degrees above the horizontal, as represented above. If air resistance is negligible, the time needed for the ball to return to the ground is most nearly

Definition

B. 1.42s

Term
