A car travels due east with a speed of 32.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 52.0° with the vertical. Find the velocity of the rain with respect to the following reference frames. (Enter the magnitude of the velocity.)
(a) the car____m/s
(b) the Earth____m/s
What is Fx of the magnitude of the skiers velocity.
An ocean liner leaves New York City and travels 34.0° north of east for 169 km. How far east and how far north has it gone? In other words, what are the magnitudes of the components of the ship's displacement vector in the subsequent directions.
An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first sees the car, the locomotive is 130 m from the crossing and its speed is 17 m/s.
During this process the arrow's deceleration has a magnitude of 1600 and the block's acceleration has a magnitude of 450. Explain how long does it take for the arrow to stop moving with respect to the block?
A girl is standing at the edge of the cliff 271 m above the ground. She reaches out over the edge of the cliff and throws a rock straight upward with a speed of 6.17 m/s. a) how long does it take the rock to hit ground? b) What is the speed of the ro..
