Question

The velocity of a particle moving in positive x-axis
is according to relation v = 4x. If at t = 0
particle is at x = 0, then the velocity and
acceleration at t = 2s are given as
(1) 4 m/s, 4 m/s2 (2) 2 m/s, 2 m/s2
(3) 2 m/s, 4 m/s2 (4) 4 m/s, 2 m/s
​

Answer 1

Answer:

(sinθ +cos θ - 1)/sinθ x (cos θ + sinθ + 1 )/cosθ = 2
