I've been trying to figure them out but can't get through about 6 questions, these are the other two..
An object is observed to fall from a bridge, striking the water below 2.50 s later. (a) With what velocity did it strike the water? (b) What was its average velocity during the fall? (c) How high is the bridge?
A ferryboat requires 45.0 min to travel 15.0 km across a bay. (a) what was the avg speed in m/s? (b) At this speed, how much time would be required for the boat to take a 420 km trip up the river?
