Final answer:
To determine the distance a cart travels in 40 seconds, the initial speed or average speed of the cart is required. With a constant speed, the distance is the product of speed and time. For example, at 1 m/s, the cart would travel 40 meters in 40 seconds.
Step-by-step explanation:
To predict the distance a cart will travel in 40 seconds, you need to know its initial speed or average speed. If we assume the cart is moving with a constant speed, then the distance traveled (d) can be found by using the formula d = vt, where v represents the speed of the cart and t is the time.
If we know the speed of the cart from a previous part of the experiment, as described in the reference information, we can calculate the distance traveled by multiplying the speed by the total time of 40 seconds.
For example, if the cart's previous speed measurement was 1 meter per second (m/s), the expected distance for the cart to travel in 40 seconds would be:
Distance (d) = Speed (v) × Time (t)
Distance = 1 m/s × 40 s
Distance = 40 meters
Without additional information on the cart's speed, we cannot give a precise answer.
