Boat

A force of 240 kg (2400 N) is required to pull a boat up a ramp inclined at 10° with horizontal.

How much does the boat weigh?

Correct answer:

m =  1382.1 kg

Step-by-step explanation:

m0=240 kg F=2400 N α=10   sin α = m0:m = F:G  m=sinαm0=sin10° m0=sin10° 240=0.173648240=1382.1=1382.1 kg
