Question

Q7
A toy car moves along a straight line
racing track the data of variation
in its velocity with given below.
Time (s) 0 20 30 40 50 60 70
Velocity (v) 0 2 4 6 8 10 12 14
Plot a velocity time graph. What can
you conclude from the graph ? Using
velocity time graph. Calculate the
acceleration of the car.​

Answer 1

Answer:

The graph would be an straight line. The velocity is increasing at the rate of 2 unit and rate of change in velocity is acceleration.

$\frac{dx}{dt} = v$

here v= velocity,

X = distance or displacement,

t = time

Explanation:

Rate of change in velocity is acceleration.

$\frac{dv}{dt} = a$
