Question

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

Answer 1

$V_{av} = \frac{v - u}{t_{f} -t_{i} } \\ \\ \: \: \: \: \: \: = \frac{8 - 2}{4 - 1} = \frac{6}{3} {ms}^{ - 1} \: \: \: \: \: \: \: or \: \: 2 {ms}^{ - 1}$

Answer 2

Explanation:
