Questions
The point from where a ball is projected is taken as the origin of the coordinate axes. The x and y components of its displacement are given by x = 6t and y = 8t - 5 . What is the velocity of projection?
detailed solution
Correct option is C
vx = dxdt = 6 and vy = dydt = 8-10t = 8-10×0 = 8 v = vx2+vy2 = 62+82 = 10 ms-1Talk to our academic expert!
