Physics Questions Two objects, A and B, are thrown up from the same level. Object A has initial speed 22.3 m/s; object B has initial speed 27.8 m/s. What is the distance between these two objects 1.6 seconds later? Two objects, A and B, are thrown up at the same moment of time from the same level (from the ground). Object A has initial velocity 11.1 m/s; object B has initial velocity 17.0 m/s. How high above the ground is object B at the moment when object A hits the ground? The pilot of an airplane traveling with constant velocity 185 m/s wants to drop supplies to the expedition isolated on a patch of land 250 below surrounded by the water, so supplies should be dropped straight to the camp. What should be the distance between plane and the camp at the moment of releasing of supplies? Hint: this question is about total distance. A driver on the motorcycle speeds horizontally off the cliff which is 70.5 m high. How fast should the driver move to land on level ground below 80.5 m from the base of the cliff? Give answer in m/s.
