If displacement is depend on time such that x = 2t –2 then find out average speed upt to 4 sec

Text Solution

Verified by Experts

Average speed`=("Total distance")/("Total time")`
for total distance
at t=0 it is at x=-2
at t=1 it is at 0m
at t=4 it is at 6m
Total distance = |– 2| + 0 + 6 = 8 m
Average speed = 8/4 = 2m/sec
