Find the distance traveled in 15 seconds by an object moving with a velocity of v(t)=20+7cos(t) feet per second.

We are given with the equation v(t)=20+7cos(t)  where v is the velocity with units feet per second and t is time in seconds. Velocity is the distance travelled by a moving object per unit time. in this case, we get first the velocity at t =15 equal to 26.76 feet per second. Distance is vt or equal to 410.42 feet.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
