Acceleration, a
= (100-50)/6 km/hr/s
= 50/3.6/6 m/s/s
=2.31 m/s²
mass = 800 kg
frictional force
= μk*N
= μk*mg
= 2352 N
force required to provide required acceleration
= ma
= 800*2.31 N
The required force is the sum of the frictional resistance and force required to provide acceleration.
What force is must a jet's boat engine apply to accelerate the boat from 50 km/h to 100 km/h in 6.0 s? The mass of the boat is 800 kg and the coefficient of kinetic friction is 0.30.
I found acceleration by doing v2-v1 / t, but im not sure what to do next?
