the velocity of a moving object, v, in meters per second, is given by the formula below. The variable is the kinetic energy of the object, in joules, and m is the mass of the object, in kilograms. A marble with a mass of 0.04 kilograms rolls down a ramp and reaches a maximum kinetic energy of 0.875 Joules. Use the given formula to write a function, v(x)c that models the situation. Then use the function to predict how the velocity of the marble changes as it rolls down the ramp

Question
Answer:
Assuming the velocity is as written,
a = 3(2) = 6

If you meant 3(2t+1)⁰.⁴, then
a = 2.4/(2t+1)⁰.⁶

as usual,
s = 25 + 1/2 at²
= 25 + 3t² 
or
= 25 + 1.2(2t+1)¹.⁴
