Question

From the v-t graph, the: Speed at t = 1 s is 1.2 m/s Acceleration is 2 m/s 2 Average speed during 1st second is 1.5 m/s Speed of the particle can be zero

Answer 1

Answer:

try through the given similar answer

Explanation:

Slope of v-t graph gives the acceleration of the particle for a given time interval.

Thus slope of line AC is equal to the acceleration of particle at t=2s.

∴ Acceleration a
