A ski lift takes a 60 kg skier to the top of a 100 m slope. Assuming her skis are frictionless, what is her speed when she gets to the bottom of the slope?

Question

superdavesuper · Answer

its really a physics Q....but u can find the speed by using conservation of energy:

mgh=(mv^2)/2

where m=mass, g=gravity, h=height and v=velocity/speed

anonymous · Answer

Thanks, but how do you calculate the answer @superdavesuper

superdavesuper · Answer

by putting in the values given in the prob. for m, g and h; then solve for v

anonymous · Answer

i dont understand how to get v alone... @superdavesuper

superdavesuper · Answer

find v^2 first....that is the only unknown in the eqn above

anonymous · Answer

so 60 x 9.8 x 100 =58800

@superdavesuper

superdavesuper · Answer

OK that is the potential energy at the top of slope. at the bottom, all that energy will be converted to kinetic energy (mv^2)/2....solve for v plz
