1 point A Kingfisher is a bird that catches fish by plunging into the water from a
height of several meters. If a kingfisher dives from a height of 8.7m with an
average speed of 4.95 m/s, how long does it take for it to reach the water.(
Average Speed = distance/time)

A1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. what is the magnitude of the friction force required to keep the car from sliding?

A12-g wad of sticky clay is hurled horizontally at a 100-g wooden block initially at rest on a horizontal surface. the clay sticks to the block. after impact, the block slides 7.5 m before coming to rest. if the coefficient of friction between the block and the surface is 0.65, what was the speed of the clay immediately before the impact?
