Question

A roadrunner is running at an initial speed of 66.6 m/s. our feathery-dinosaur buddy sees a tasty lizard snack and bolts towards it accelerating at 12 m/s² for 2.4 seconds. what is the majestic birds' final velocity in m/s? round to the nearest whole number.

Answer 1

The roadrunner's final velocity is approximately 95 m/s.

Step-by-step explanation:

To find the final velocity of the roadrunner, we can use the equation: v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.

Given that the initial velocity (u) is 66.6 m/s, the acceleration(a) is 12 m/s², and the time(t) is 2.4 seconds, we can substitute these values into the equation to find the final velocity.

v = 66.6 + (12 × 2.4) = 66.6 + 28.8 = 95.4 m/s

So, the roadrunner's final velocity is approximately 95 m/s.
