Question

A body moves in a straight line along x-axis its distance from the origin is given {x=8t-3t^2} unit of x is meter and the unit of t is second:
find the average velocity in the interval
1)t=0 to t=1
2)t=0 to t=4

Answer 2

Answer:

Given: y=8t−3t ^2

Average speed = total distance/total time

Total distance =8(1)−3(1 ^2 )=5 m

Total time =1 sec

⇒Average speed = 5/1

=5 m/s
