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.
Based on the recorded observations, what is the mass of the go-cart in kilograms? (F=ma)
a
28.8 kg
b
20 kg
c
45 kg
d
5 kg
To determine the mass of the go-cart, we can use the formula F=ma, where F is the force and a is the acceleration. By rearranging the formula, we can calculate the mass as m=F/a.
Looking at the data, we can see that when the force is 144 N, the acceleration is 5 m/s². Plugging these values into the formula, we get m=144 N/5 m/s² = 28.8 kg.
Therefore, the mass of the go-cart is 28.8 kg.
The correct answer is a) 28.8 kg
