Question

Boy throws a ball in a train moving at a speed of 18kmph with a velocity of 15 root 2 metre per second at an angle of 45 degree to the horizontal in the direction of motion of the train that angle with which it strikes the plane of projection with respect to an observer watching from the road near by the train is​

Answer 1

Answer:

37°

Explanation:

18 kmph=5 m/s

v(x)=15+5=20{velocity along x before collision}

v(y)=15{velocity along y before collision is same as u(y) with opposite sign}

now tan(Q)=v(y)/v(x)=15/20=3/4

so answer is 37 degrees
