Question
Nikolas had an idea that he could use the compressed carbon dioxide in a fire extinguisher to propel him on his skateboard. Nikolas, the fire extinguisher and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to produce to propel Nikolas if he wanted to accelerate at a rate of 1.2m/s^2 Round your answer t the nearest whole newton. square N

60 N
Explanation
To solve this problem, we will use Newton's second law of motion, which states that the force exerted on an object is equal to the mass of the object multiplied by the acceleration of the object (F = ma). In this case, the mass (m) of Nikolas, the fire extinguisher, and the skateboard combined is 50 kg, and the desired acceleration (a) is 1.2 m/s^2. By multiplying these two values, we can find the force (F) that the fire extinguisher needs to produce.Let's calculate it:F = maF = 50 kg × 1.2 m/s^2F = 60 NSince we need to round the answer to the nearest whole Newton, the force the fire extinguisher would need to produce is 60 Newtons.
