Question

Given a velocity time graph for the motion of the car. What
does the nature of the graph shows? Also find the accelerat
of the car from A to B in graph.
​

Answer 1

Acceleration = Slope of v-t graph

$slope \: = \frac{change \: in \: y}{change \: in \: x} = \frac{change \: in \: velocity}{change \: in \: time} \\ slope \: = \frac{10 - 7.5}{20 - 15} = \frac{2.5}{5} = 0.5m {s}^{ - 2}$

The graph shows that the body is in constant acceleration of 0.5m/s²
