Question

An object moves along the y axis according to the equation y(t) = b + ct³, where b = 2.70 m, c = 2.20 m/s³, and y(t) will be in meters when t is entered in seconds. Determine the following. (a) average velocity of the object during the time interval t = 1.00 s to t = 3.00 s m/s (b) instantaneous velocity at the time t = 2.00 s m/s (c) acceleration of the object at the time t = 2.00 s m/s² (d) In this case, the average velocity over the time interval t = 1.00 s to t = 3.00 s is not equal to the instantaneous velocity at the midpoint of the time interval (t = 2.00 s) because of which of the following? The acceleration is not a constant. The acceleration is negative. The acceleration is positive. The average velocity is never equal to the instantaneous velocity.

Step 1

00 to 3.00 seconds. Given: - Initial position at t = 1.00 seconds, y(1.00) = 4.90 m - Final position at t = 3.00 seconds, y(3.00) = 62.1 m Average velocity formula: \[ \text{Average velocity} = \frac{y(3.00) - y(1.00)}{3.00 - 1.00} \] Substitute the values: \[ Show more…
