... 2. GRR1 5.P.006. An elevator cable winds on a drum of radius 70.0 cm that is connected to a motor. (a) If the elevator is moving down at 0.60 m/s, what is the angular speed of the drum? The speed of the elevator must be the speed of the rope as it leaves the drum. Since the rope is unspooling from t ...

... A cart is moving with a constant horizontal velocity of 5.00 m/s. A small pebble is launched from the front of the cart with a velocity of 8.00 m/s at 60.0° above the horizontal as measured relative to the cart (see figure) and experiences no significant air resistance. Just as the pebble returns to ...

... In the question the velocity upwards is positive, and I’ll keep it that way. That just means that I have to make sure that I use gravity as a negative number, since gravity always acts down. vf = vi + at = 56.3m/s + (-9.81m/s2)(4.52s) vf = 12.0 m/s This value is still positive, but smaller. The bal ...
