Aparticle traveling at 7.4 m/s decelerates at 1.3 m/s 2 . how long will it take to get back to the starting point?

Time taken, t = 5.69 seconds

Explanation:

It is given that,

Initial speed of the particle, u = 7.4 m/s

Deceleration of the particle,

We need to find the time taken by it to get back to the starting point. Let t is the time taken. So,

t = 5.69 seconds

So, the time taken by the particle is 5.69 seconds. Hence, this is the required solution.
