Question

a particle passes given point moving down words with velocity of 50 metre per second how long before this was it was moving at the same rate​

Answer 1

Answer:

10 Sec

Explanation:

a particle passes given point moving down words with velocity of 50 metre per second how long before this was it was moving at the same rate​

PArticle moving at 50 m/s Downward

With acceleration = g = 10 m/s

Before T time then it must be moving with Velocity upward of 50 m/s

(for being at same Rate)

Using V = U + aT

=> 50 = -50 + (10)T

=> 10T = 100

=> T = 10 sec

10 Sec before it was moving with same rate but upward
