Question

A particle is moving on a straight line with speed
v = (30t^2 + 4t + 2) (where v is in m/s and t is in s).
The average speed from t = 0 to t = 5 s is
(1) 777 ms-1
(2) 262 ms-1
(3) 304 ms
(4) 304 ms-1​

Answer 1

Answer:

300.333.. m/s

Explanation:

Velocity at T=0 is 2

Velocity at T=1 is 36

Velocity at T=2 is 130

Velocity at T=3 is 284

Velocity at T=4 is 498

Velocity at T=5 is 852

Total velocity 1802m/s

Average speed = 1802/6

Average speed = 300.333...
