The second law of motion states that force is equal to mass times acceleration. how much more force would be required to accelerate a fifty-ton ship at the same rate as a ten-ton ship? the same
two times
five times
ten times

Newton's second law:

F = ma

F = net force, m = mass, a = acceleration

Isolate a:

a = F/m

We can see that for an object with larger mass, we would need to apply a larger force on it to accelerate it at the same rate.

Compared to the 10 ton ship, we would need 5 times more force to accelerate a 50 ton ship at the same rate.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

in physics zero. in muscle fatigue could be high
