Question

an object starts its Motion from rest attains 50 metre per second speed in 10 seconds draw VT graph from this graph and calculate displacement and acceleration​

Answer 1

Answer:

a = v-u/t

v = 50m/s

u = 0 ( as it has started from rest)

a =?

Explanation:

a = 50-0/10

a =5m/s^2

Hence, the acceleration would be 5m/s^2

For the displacement,we would use the 2nd equation of motion

Given,

v = 50m/s

u = 0

a = 5m/s^2

t = 10s

S = ut + 1/2 at^2

S = 0*10 + 1/2 * 5*100

S = 0 + 250

S = 250m/s

Therefore,the displacement covered by the object is 250m and the acceleration attained is 5m/s^2
