Question

a) Calculate the acceleration of the body and
b) Draw the acceleration-time graph.​

Answer 1

• initial velocity=u=7.5m/s
• Final velocity=v=10m/s
• Time=t=5s

We know

$\boxed{\sf Acceleration=\dfrac{v-u}{t}}$

$\\ \sf\longmapsto Acceleration=\dfrac{10-7?5}{5}$

$\\ \sf\longmapsto Acceleration=\dfrac{2.5}{5}$

$\\ \sf\longmapsto Acceleration=0.5m/s^2$
