Question
A body is projected at some angle with a velocity of 100m/s and it takes 5 second to reach the ground. The change in its velocity for the whole motion is ........ [g=10 m/s2]
Read 2 Solution.
t = 2usinθ/g from this find the angle , then find change in vel
by the way horizontal will cancel out ,u will left with vertical component add it up ie 2vsinθ
