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
WY4 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/s2
ation is having
​

Answer 1

Answer:

explanation:

v = 4x = dx/dt

=> dx / x = 4dt

=> ln(x) = 4t

=> x = exp(4t)

Now,

V = dx/dt = 4 exp(4t)

a = dv/dt = 16 exp(4t)
