Question

The position x of a particle as function of time t is given by the relation t = x + 3 ( where x is in metre and t is in seconds ). The velocity of particle at 2 seconds is
1) 1 m/s
2) 2 m/s
3) 4 m/s
4) -3 m/s

Answer 1

Answer:

1 m/s

Explanation:

As the given equation is

t=x+3

or x=t-3

now differentiate the above equation with respect to time t, we get

dx/dt = dt/dt - d/dt (-3)

or v = 1-0

or v = 1 m/s

As velocity is constant as it is a linear function of time.

Hope it helps.
