Question

Ek bus ki gati 5 second Mein 80 kilometre Prati Ghanta se ghatghar 60 kilometre Prati Ghanta Ho Jati Hai Uska tawaran gyat Karen

Answer 1

Answer: The acceleration of the bus is -1.11 m/s²

Explanation:

Initial velocity u = 80 km/h = 22.22 m/s

Final velocity v = 60 km/h = 16.67 m/s

Time t = 5 sec

We need to calculate the acceleration

The acceleration is defined as,

Using equation of motion

.....(I)

Put the value of v,u and t in equation (I)

we get a=-1.11 m/s²

Negative sign shows the retardation.
