Question

10. Acceleration-time graph of a particle, whose initial
velocity is 10 ms), is shown in the figure 2.25,
What is the velocity of the particle at t=5 s, 10 s and 20 s?
[ 60 m s!, 160 m s', 60 m s']​

Answer 1

Answer:

At t=5and 20s the velocity will be 60m/s while at t=10s the velocity will be 160m/s.

Explanation:

Area under a/t graph gives change in velocity.

At t=5s the area will be 50units that is your at.

Now using the equation v=u+at. We can find that at t=At t=5and 20s the velocity will be 60m/s while at t=10s the velocity will be 160m/s.
