Question

A particle, starting at rest, accelerates at 5 m/s2 for 10 s. It then decelerates to 30 m/s over a period of 10 s. The particle then moves at a constant speed for 20 s before decelerating to zero over a period of 5 s.

6. (12 points) A particle, starting at rest, accelerates at 5 m/s for 10 s. It then decelerates to 30 m/s over a 0 s. The particle tl of 5 s Plot the velocity and acceleration of the particle as functions of time. What is the total distance traveled by the particle?
