Question

21. A body moving with uniform acceleration is having
velocity 2 m/s and 8 m/s at t = 1 s and t = 4 s
respectively. Then average velocity of particle in the
time interval t = 1 s to t = 4 s is
(2) 3 m/s
(1) 2 m/s
*7
(3) 5/3 m/s
(4) 5 m/s​

Answer 1

Answer:

ok

Answer 2

Answer:

2m/s

Explanation:

avg velocity=∆x/∆t=8-2/4-1 =6/3=2m/s
