Question

A bike is moving with velocity $v$ and time$t$, data as shown on the following table.Here negative time means time before the starting of observation.
Choose the correct option(s).

• A. Distance covered at time -2$s$ is 12$m$
• B. Distance covered at time 4$s$ is 40$m$
• C. Distance covered at time -2$s$ is -12$m$
• D. Distance covered at time 0$s$ is 0$m$

Answer 1

Answer: (A), (B), (D)

The correct options are
A Distance covered at time -2$s$ is 12$m$
B Distance covered at time 4$s$ is 40$m$
D Distance covered at time 0$s$ is 0$m$

We know that,

$Distance=Time\times Velocity$

Distance covered by bike at time 0$s$ and velocity 2$m{s}^{-1}$ = 0 $\times$ 2 = 0$m$

Distance covered by bike at time 1$s$ and velocity 4$m{s}^{-1}$ = 1 $\times$ 4 = 4$m$

Distance covered by bike at time -2$s$ and velocity -6$m{s}^{-1}$ = -2 $\times$ -6 = 12$m$

Distance covered by bike at time -3$s$ and velocity -8$m{s}^{-1}$ = -3 $\times$ -8 = 24$m$

Distance covered by bike at time 4$s$ and velocity 10$m{s}^{-1}$ = 4 $\times$ 10 = 40$m$

Distance covered by bike at time -5$s$ and velocity -12$m{s}^{-1}$ = 4 $\times$ 10 = 60$m$
