Question

1. A block moves from A to B in two equal time
intervals with velocity 10 m/s and 20 m/s
respectively. The magnitude of average velocity from
A to B will be
10 m/s
20 m/s
(1) 0 m/s
(3) 6 m/s
12) 15 m/s
(4) 10 m/s
​

Answer 1

Avg velocity for 2equal interval of time = v1+v2/2 (for proof comment)
=10+20/2
Answer is 15m/s

Answer 2

Answer:

15m/s

Explanation:

avg velocity=(Va +Vb)/2

=(10+20)/2

=15m/s
