Question

The velocity of an object increases at a constant rate from 20m/s to 50m/s in 10 seconds.what is it's acceleration?


Please answer quickly

Answer 1

Answer: u = 20 m/s

v = 50 m/s

t = 10 s

a = v - u

t

= 50-20

10

= 30

10

= 3 m/s^2

Acceleration = 3 m/s^2

Answer 2

✰Question ✰

▪The velocity of an object increases at a constant rate from 20m/s to 50m/s in 10 seconds.what is it's acceleration

✰Answer ✰

➧ Given:-

▪ Initial velocity of object (u) =20m/s

▪Final velocity of object (v) =50m/s

▪Time taken (t) =10 second

➧ To Find :-

Acceleration of object????

➧Solution

➠ By using first equation of motion

$v = u + at \\ \\ 50 = 20 + a \times 10 \\ \\ a = \frac{50 - 20}{10} \\ \\ a \: = 3m \: per \: second \: sq.$

∴The required answer is 3m/s^2

✰Additional information ✰

➠The rate of change of velocity at per unit time is called acceleration.

➠ SI unit of acceleration is m/s^2
