Which of the following is not a unit of power? a)hp b)J c)W d)J/s I answered d. J/s because its measuring speed and not power. I don't know if its correct or not.

Whats the equation?? I haven't done this is a while. Don't show me the answer i want to figure it out cus that's just how i roll thanks! A car accelerates uniformly from 10 m/s to 20 m/s in 4.2 seconds. What is the magnitude of its acceleration? Do i time...

Okay the equation for kinetic energy is = 1/2mv^2 so how would i figure this out?? If a semi-truck decreases its speed from 10 m/s to 5 m/s, its new Kinetic Energy is: a)4 times its old Kinetic Energy b)2 times its old Kinetic Energy c)1/2 its old Kinetic...

I have no idea what does this have to do with physics but hope you can explain... A passenger on a bus moving east sees a man standing on a curb. From the passenger's perspective, the man appears to be... a)stand still. b) move west at a speed that is les...

Thank you:)

i don't know how?(:<

d = v^2/(2a) d = 9.6^2/(2(9.81)) d = 4.7 m haha i answered it myself

thanks yu:))))))))))))))))))))))))))

so its 10*9.8*25? It that right?

Thanks!
