Question 23
Trial Force (N) Acceleration (m/s^2)
1 10 N 2.5
2 12 3
3 22 5.5
Students are running an experiment in which they are measuring the acceleration after applying forces to a cart. Using the data above, what is the mass of the cart?
a
2 kg
b
4 kg
c
6 kg
d
8 kg
To determine the mass of the cart, we can use Newton's second law, which states that force (F) is equal to mass (m) times acceleration (a):
F = ma
From the given data, we can see that the force (F) and acceleration (a) are directly proportional to each other:
10 N / 2.5 m/s^2 = 4 kg
12 N / 3 m/s^2 = 4 kg
22 N / 5.5 m/s^2 = 4 kg
Therefore, the mass of the cart is 4 kg.
The correct answer is: b) 4 kg
