A 1000Kg auto travels up a 3 percent grade at 20m/s. Find the horsepower required, neglection friction.(adsbygoogle = window.adsbygoogle || []).push({});

ok HP, that means power formula

work/time right, or f * v

how do i approach here

i wanted to do v2 squre = v1 square + 2 ad. but i dotn know if v1 is 0 and is distance (3/100)?

i did that and i got a wierd acceleration number, plugged that into f = ma, got force and mulitplied that by V which is 20 and i got the wrong answer, any ideas?

thanks
