Acceleration increases over time once a force is applied to the object. determine the acceleration at 3.5 sec? a) 3 m/s2 b) 6 m/s2 c) 15 m/s2 d) 53 m/s2

Acceleration does not increase over time once a force is applied to the object. It depends on the force and the object's mass. If those don't change, then the acceleration is constant.

Explanation:. F = M • a

We don't know either of those numbers, so we can't answer the question.

the answer is b, have negligible mass

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
