If force F=500-100t, then function of impulse with time will be,-

A

`500t-50t^(2)`

B

50t – 10

C

`50 – t_(2)`

D

`100t^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`because F = (dP)/(dt) implies Fdt = dp`
`DeltaP = Impulse = int_(0)^(t)Fdt =int_(0)^(t)(500-100t)dt`
= `500t-50t^(2)`
