The object must have stopped moving The object must be slowing down. The object must be moving with constant velocity.
What is the acceleration of a projectile when its instantaneous vertical velocity is zero at the top of its trajectory? Ozero -9.8 m/s² No answer text provided. 4.9 m/s² 9.8 m/s²
Which of the following is NOT TRUE about a cannonball launched horizontally if air resistance is neglected? The distance the cannonball travels is dependent on its mass The cannonball has a uniform horizontal velocity. The speed of the cannonball increases as a function of time The vertical velocity of cannonball increases as a function of time Onone of the given choices
A tennis ball is thrown with an initial velocity of 15.0 m/s at an angle of 60.0° above the horizontal. If air resistance and wind are neglected, the ball will fall m horizontally from the point of release. 15.0 m 18.4 m Ⓒ20.0 m 22.1 m
