Arthur and Betty start walking toward each other when they are 100. m apart. Arthur
has a speed of 3.0 m/s and Betty has a speed of 2.0 m/s. Their dog, Spot, starts from
Arthur's side at the same time and runs back and forth between them. By the time Arthur
and Betty meet, what is Spot's displacement?
A bunch of keys was thrown directly upward by Macoy, who is looking out of the window, to be caught by Len-Len living on a room right above him. Unfortunately, Len-Len wasn't able to catch the keys and therefore the bunch of keys went straight to the ground. If Macoy gave the keys an upward speed of 3 m/s and the keys reached the ground after Macoy threw the keys upward in 4 seconds,
the speed of the keys just before it reached the ground is 36.2 m/s the height of his room from the ground is 66.4 m
c. What is the keys' acceleration when it reached its highest point?d. What is the keys' velocity when it reached its highest point?
A girl is standing at the edge of a cliff 100. m above the ground. She reaches out over the edge of the cliff and throws a rock straight upward with a speed 8.00 m/s. a) How long does it take the rock to hit the ground? b) What is the speed of the rock the instant before it hits the ground?
