A particle is projected with a velocity of 50 m/s at `37^@` with horizontal. Find velocity, displacement and co-ordinates of the particle (w.r.t. the starting point) after 2 s.
Given, `g=10m//s^2, sin 37^@ = 0.6 and cos 37^@ = 0.8`.

Options

A. `(40hati + 10hatj) m//s` `x=80 m and y= 80m`
B. `(40hati + 10hatj) m//s` `x=20 m and y= 40m`
C. `(40hati + 10hatj) m//s` `x=80 m and y= 40m`
D. `(40hati + 20hatj) m//s` `x=80 m and y= 40m`

Answer

C
