Question

The velocity of a body depends on time as
v(in m/s) = 20 + 5t(in s). The average velocity of
the body between t = 1 s to t = 3 s is
(1) 20 m/s
(2) 25 m/s
(3) 30 m/s
(4) 35 m/s​

Answer 1

Answer:

Explanation:

V=20+5t

So,v=20+5(3-1)

=20+5*2

=30m/s

Hence third option is correct

Answer 2

Answer:

answer is option-3

30m/s

Explanation:

Velocity defines the path of the motion of the frame or the item. The pace of a transferring item may be zero. Speed is a top indicator of the rapidity of the item. Velocity is the top indicator of the location in addition to the rapidity of the item.

SI unit: m/s

Dimension: LT−1

Other units: mph, ft/s

V=20+5t  

So,v=20+5(3-1)  

=20+5x2

=30m/s
