Answer:
2.5 m/s²
Explanation:
Figure given below shows the graph of velocity v of particle moving along x-axis as a function of time t. Average acceleration during t = 1 s to t = 7 s is
Velocity at t = 0 is 0 m/s
Velocity at t = 2 is 20 m/s
a from t = 0 to 2 sec = (20 - 0)/2 = 10 m/s²
Velocity at t = 1 sec = 0 + 10*1 = 10 m/s
Velocity at t - 6 sec = 20m/s
Velocity at t - 8 sec = 30m/s
a from t 6 - 8 sec = (30 - 20)/(8-6) = 10/2 = 5 m/s²
Velocity at t = 7 sec = 20 + 5*1 = 25 m/s
Velocity at t = 1 sec = 10 m/s
Velocity at t = 7 sec = 25 m/sec
Average acceleration from t = 1 to 7 sec = (25 -10)/(7-1) = 15/6
= 2.5 m/s²
