Velocity-time graph for a body moving wi...

Velocity-time graph for a body moving with retardation is shown. Calculate the (i) retardation and (ii) displacement of the body.

Text Solution

Verified by Experts


(i) Here, retardation=`("Decrease in velocity")/("time taken")`
`=((10-0)m//s)/((5-0)s)=(10)/(5)m//s^(2)=2m//s^(2)`
(ii) Displacement=Area of velocity-time graph
=Area of `DeltaAOB`
`=(1)/(2)xxOBxxOA=((1)/(2)xx5xx10)m=25`m.
