for the second one I have no idea where to even begin P=5000W or J/s v= 5.0m/s So I originally tried figuring out force which you can get by doing F = P/ V = 5000W/5.0m/s = 1000N and I believe you can find the mass of that by dividing the 1000N/9.8 = 102.04kg is that it or is...

ok well for the first one...we did something similar in class, but when I tried it, it was definately wrong. we were told to not include mass when it is not given so for this it would be: Eg = mg x h Ek= 1/2mv2 = m(9.8)(3.5) =(0.5)m(3.0)2 =34.3mJ...

Ok so I'm in Gr 11 U Physics and we have an assignment and I have a couple q's 1) While at the park a child sits on top of a 3.5m slide. When he reaches the bottom of the slide, he is traveling at 3.0m/s. Calaculate the efficency of the slide 2) A 5000 W motor is lifting crates from the...
