Answer:
x ≈ 14.7
Step-by-step explanation:
use pythagorean therorem
a^2 + b^2 = c^2
c is hypotenuse and we know the hypotenuse is 21
a^2 + b^2 = c^2
x^2 + 15^2 = 21^2
x^2 + 225 = 441
x^2 = 216
x = √216
x ≈ 14.7
To get the acceleration without time or speed you Do the force/kgs divided by the mass/N to get the acceleration. Which s 3.2 mph Forces being used: Force A is the force that is fighting the weight of the ship then there is Force B that is left over and lifts the ship.
