Question

A car accelerates uniformly (a = constant) from 34 meters/second up to 40 meters/second in 4.0 seconds. What is the acceleration of the car in meters/second2?

Answer 1

3.5 seconds

Answer 2

. If a car is already going 50 m/s, and it accelerates at 2 m/s/sec for 15 seconds, how fast will it be going?

Answer 3

[AI-generated answer — Explain Bot]

To find the acceleration of the car, you need to use the formula for acceleration:

a = (v_f - v_i) / t

where:
a is the acceleration
v_f is the final velocity
v_i is the initial velocity
t is the time taken

Given that the initial velocity (v_i) is 34 m/s, the final velocity (v_f) is 40 m/s, and the time taken (t) is 4.0 seconds, we can plug in the values into the formula:

a = (40 - 34) / 4.0

Now, let's do the math:

a = 6 / 4.0
a = 1.5 m/s^2

Therefore, the acceleration of the car is 1.5 meters/second^2.
