Question

A particle is executing SHM about y = 0 along y-axis. Its position at an instant is given by y=7sinπt
Its average velocity for a time interval 0 to 0.5 s is
(1) 14 m/s
(2) 7m/s
​

Answer 1

Answer:

hopefully it will help u..if any doubts feel free to ask

Answer 2

The average velocity is 14 m/s.

(1) is correct option.

Explanation:

Given that,

The position equation is

$y=7\sin\pi t$

Time interval = 0.5 sec

The position of the particle y = 0 at t = 0

The position of particle y =7 m at t = 0.5 sec

The total displacement is 7 m.

We need to calculate the average velocity

Using formula of average velocity

$v=\dfrac{D}{T}$

Where, D = Total displacement

T = Total time

$v=\dfrac{7}{0.5}$

$v=14\ m/s$

Hence, The average velocity is 14 m/s.
