Kinda confused, so do I do 1/2mv² to find the kinetic and then mgh for potential?

I know the cage gained 1.25*10⁵J of gravitational potential energy between C and D (just added that to the main question)

1. Homework Statement In a theme park ride, a cage containing passengers falls freely a distance of 30 m from A to B and travels in a circular arc of radius 20 m from B to C. Assume that friction is negligible between A and C. Brakes are applied at C after which the cage with its passengers...

Oh of course mass doesn't taken into account gravity, I understand now. Thank you!

I assume you'd do Sin3.8*70 as in Opp=Sinθ*hyp however that left me with the answer 4.6 not 46. (thanks for helping btw)

Ah ok thanks

Yeah I did try that but ended up with 4.6 not 46. I did Sin3.8*70 and got 4.6 so I'm not sure if my angle is wrong?

Homework Statement A cyclist rides along a road up an incline at a steady speed of 9.0 m s–1. The mass of the rider and bicycle is 70kg and the bicycle travels 15 m along the road for every 1.0 m gained in height. Neglect energy loss due to frictional forces. Calculate the component of the...
