A hot air balloon moves up at constant speed v= 10.0m/s. When the balloon is 20.0 meter above the ground, a cup is lemonade falls out of the ballon and the ballon continues to move up at a constant speed v=10 m/s. Ignore the air resistance. Choose upward as the positive direction and t=0 when the cup starts to fall out of the balloon. A) Describe the motion of the lemonade cup as relative to the ground. Indicate the initial position, initial velocity and acceleration of the cup B) Describe the motion of the lemonade cup as relative to the balloon. Indicate the initial position, initial velocity and acceleration of the cup C) on the same diagram, plot the v-t graph of the ballon and the v-t diagram of the lemonade cup as relative to the ground. D) what is the impact velocity of the cup as relative to the ground when it hit the ground
