Find the velocity, v(t), for an object moving along the x-axis if the acceleration, a(t), is a(t) = 2t + sin(t) and v(0) = 4. (4 points)

A.) v(t) = t2 + cos(t) + 3

B.) v(t) = 2 + cos(t) + 1

C.) v(t) = t2 - cos(t) + 5

D.) v(t) = t2 + sin(t) + 4

Please Help! I think the answer is D

The answer is (c) v(t) = t² - cos(t) + 5

Step-by-step explanation:

Given the acceleration a(t) = 2t + sin(t), we can calculate the velocity. Acceleration(a) is the time rate of velocity(v), it is the differential of velocity with respect to time(t) and is given by the equation:

cross multiplying, we get

Therefore

To calculate v(t) we integrate both sides

therefore , but a(t) = 2t + sin(t)

to get c At t = 0, v(0) = 4

substituting c = 5 we get

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
