Question

A body moving with 20m/s turns by 60° and continuous with 20m/s.Find change in velocity​

Answer 1

Answer:

20m/s

Explanation:

V=20m/s,, Theta=60 degree

2vsin theta÷2

2×20×sin60÷2

2×20×sin30

2×20×1÷2

20m/s

When both vectors are the same in magnitude and the angle between them is less than 90 degrees then we can solve the question with the help of this formula 2×v×sin theta÷2
