The acceleration of a particle is 1 m / S2 in the first second and 1 m / S2 in the second second - 1m / S2, the third is 1m / S2, and the fourth is - 1m / S2. After 100 seconds, the particle displacement is "average velocity in 100 seconds" and "instantaneous velocity at the end of 100 seconds"?

The acceleration of a particle is 1 m / S2 in the first second and 1 m / S2 in the second second - 1m / S2, the third is 1m / S2, and the fourth is - 1m / S2. After 100 seconds, the particle displacement is "average velocity in 100 seconds" and "instantaneous velocity at the end of 100 seconds"?

The velocity time diagram shows that the displacement of every second is 0.5m. After 100s, the particle displacement is 50m
It can also be concluded that the average speed per second is 0.5m/s
The average velocity is 0.5m/s in 100s
The velocity time diagram shows that the velocity in odd seconds is 1 m / s and that in even seconds is 0 m / s
The instantaneous velocity at the end of 100s is 0 m / s
