Homework Statement
A 65-kg worker at a bakery loses his balance and falls 4.0 m before hitting the surface of a large vat of cake batter. He continues to travel downwards an additional 2.0 m before the cake batter finally brings him to rest. Calculate the work done on the worker by the cake batter.
Homework Equations
F = ma
ΔKE = Wnet
W = Fscosθ
PEgravity = mgh
The Attempt at a Solution
ΔKE = KEfinal - KEinitial = 0 - KEinitial ⇒ KEintitial = -(1/2)mv^2
PEgravity = mgh = (65 kg)(9.80 m/s^2)(4.0 m) = 2548 J
