Question

a body starts from rest and acquires a velocity of 10m/s in 5s. calculate the acceleration and distance travelled.​

Answer 1

Explanation:

Since a body starts from rest so

Initial velocity (u)=0 m/s

Final velocity (v)= 10m/s

Time taken to acquire velocity (T)=2 seconds

Acceleration(A)=change in velocity/time taken

V-u/T. =10–0/2 =5m/s^2

Hence accelration is 5m/s^2.

Answer 2

To Find:-

• Find the acceleration and distance travelled.

Given:-

• A body starts from rest and acquires a velocity of 10m/s in 5s.

Solution:-

u = 0 ; v = 10m/s ; t = 5sec ; a = ? ; s = ?

v = u + at

️ ➭ 10 = 0 + 5a

️ ➭ 10 = 5a

️ ➭ a = 10/5

️ ➭ $\tt\boxed { \: a \: = \: 2m/s² \: }$

So,

️ ➭ s = ut + 1/2 at²

️ ➭ s = 1/2 × 2 × 5 × 5

️ ➭ $\tt\boxed { \: s \: = \: 25m \: }$
