Question
A particle of mass ′M′ is moved under a constant power P0. At some instant after the start, its speed is v and at a later instant the speed is 2v. Neglecting friction, distance travelled by the particle as its speed increases from v to 2v is :-
Options
A.
B.
C.
D.
Solution
P0 = Fv = M
P0dx = 
Mv2dv ⇒ P0x = 
[(2v)3 - v3]
P0dx = Mv2dv ⇒ P0x = [(2v)3 - v3]Create a free account to view solution
