Can someone please help?? I Already did number 1 and 2 . Please help!!

3a) w = mg = 60 x 10 = 600N
b) W = fd = 600 x 10 = 6000J
c) chemical to gravitational potential via the mechanical pathway

4a) W = fd = 200 x 0.5 = 100J
b) chemical to kinetic via mechanical pathway

5a) F = W/d = 40000/20 = 2000N
b) some is transferred into the thermal store, some is dissipated into the surrounding

Potato’s are the right way to go promise not apples i’m 5

All are great precautions but you can still lift lighter and different muscles in between hard workdays. this keeps other muscles not usually used in shape.
