True or False: a projectile accelerates only in the y (vertical) direction. The "x," or horizontal acceleration is equal to zero.

What should the power status of a circuit be when measuring resistance with an ohmmeter?

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.
