What force accelerates a 500 kg object at 5 m/s2? a. 25000 n b. 2000 n c. 250 n d. 2500 n
me !

Apply Newton's second law of motion:

F = ma

F = force, m = mass, a = acceleration

Given values:

m = 500kg

a = 5m/s²

Plug in and solve for F:

F = 500(5)

F = 2500N

Choice D

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
