please please help with questions 77,78,79 and 80
77. A ball rolls down'a curved ramp, as shown in the Which dotted line best represents the path of 78. Above a flat horizontal plane, arrow A is shot per second, as shown in the following diagram. horizontally from a bow at a speed of 20 meters following diagram. the ball after leaving the ramp? A second arrow B is dropped from the same height and at the same instant as A is fired B. Horizontal plane Compare the amount of time A takes to strike the plane to the amount of time B takes to strike the plane. [Neglect friction.] 79. A rock is thrown horizontally from the top of a cliff at 12 meters per second. Calculate the time required for the rock to fall 45 meters vertically- 80. A ball is thrown horizontally at a speed of 24 meters per second from the top of a Cim. If the ball hits the ground 4.0 seconds later, approximately how high is the cliff? (1) 6.0 m (2) 39 m (3) 78 m (4) 96 m
