no.1 with explanation please When a train's velocity is 12.0 m/s eastward,raindrops that are falling vertically with respect to the earth maketraces that are inclined 30.0° to the vertical on the windows of the train.(a) What is the horizontal component of a drop's velocity with respectto the earth? With respect to the train? (b) What is the magnitude ofthe velocity of the raindrop with respect to the earth? With respect tothe train?A motorboat going downstream overcame a raft at a point A;T- 60 min later it turned back and after some time passed the raftat a distance I- 6.0 km from the point A. Find the flow velocityassuming the duty of the engine to be constant.A cannon fires successively two shells with velocity v-= 250 m/s; the first at the angle 0, = 60° and the second at the angle0, = 45° to the horizontal, the azimuth being the same. Neglectingthe air drag, find the time interval between firings leading to thecollision of the shells.

When a train's velocity is 12.0 m/s eastward, raindrops that are falling vertically with respect to the earth make traces that are inclined 30.0° to the vertical on the windows of the train. (a) What is the horizontal component of a drop's velocity with respect to the earth? With respect to the train? (b) What is the magnitude of the velocity of the raindrop with respect to the earth? With respect to the train?
