A float plane lands on a river. Assume the velocity of the airplane relative to the air is 35 m/s, due east; the velocity of the wind is 17 m/s, due north; and the current in the river is 5 m/s, due south.
Calculate the velocity of the plane just before it lands relative to the water.
Calculate the magnitude in m/s
Calculate direction in degrees to the north of east.
A 369 g ball moving at -27 m/s is hit by a bat. The ball moves in the opposite direction at 35 m/s. How long did it interact with the bat if the average force was 278 N
A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope angle of 20.0degree, and the man pulls upward with a force of magnitude 385N whose direction makes an angle of 30.0 degree with the ramp.
