In a series of controlled experiments, a student measures the force acting on a go-cart and the go-cart's acceleration. The student's data are shown below.

Question

Force Acceleration
(N) (m/s^2)
10 0.5
24 1.2
30 1.5

Based on the record observations, what is the mass of the go-cart in kilograms? (F=ma)
A. 5kg
B. 20 kg
C. 45 kg
D. 28.8 kg

Answer 1

To find the mass of the go-cart, we can use the formula F = ma, where F is the force and a is the acceleration.

Let's use the first data point: 10N = m * 0.5m/s^2.

Rearranging the equation, we have m = 10N / 0.5m/s^2 = 20kg.

Therefore, the mass of the go-cart is 20kg.

The correct answer is B. 20 kg.
