- Homework Statement
- The question says to find the relation between displacement and time when power remains constant.

- Relevant Equations
- Power P = F x v,where F is force and v is velocity.

Power P = F x v,where F is force and v is velocity,

if power remains constant then i think force can not remain constant as it will change the velocity v,

but the solution I found is,

F = ma, v = at,

so, P = F x v = ma x at = ma2 t,

after that calculus comes to show that displacement is directly proportional to t to the power 3/2,

my question is if a is constant, how can power remain constant,

thanks.
