Answer:
6.62s
Explanation:
Metric unit conversion:
364 g = 0.364 kg
789 g = 0.789 kg
Starting from rest, the cart takes 4.49 s to travel a distance of 1.43 m. We can use the following equation of motion to calculate the constant acceleration


Using Newton's 2nd law, we can calculate the force generated by the fan to push the 0.364 kg cart forward

Now that more mass is added, the new acceleration of the 0.789 kg cart is

We can reuse the same equation of motion to calculate the time it takes to travel 1.43 m from rest
