3) What is the net force needed to accelerate a 5800g object 6.2 ms-2 ? (make sure you have the correct units)
To calculate the net force needed to accelerate an object, we can use Newton's second law of motion, which states that force (F) is equal to the mass (m) of the object multiplied by its acceleration (a). This can be mathematically represented as F = m * a.
In this case, we are given the mass of the object as 5800g. However, it is generally better to work with mass in kilograms instead of grams. Therefore, we need to convert the mass from grams to kilograms. We know that 1 kilogram (kg) is equal to 1000 grams (g), so we can convert the mass by dividing it by 1000:
Mass = 5800g / 1000 = 5.8 kg
Now that we have the mass in kilograms, we can calculate the net force needed. We are also given the acceleration as 6.2 m/s^2. Substituting the values into the formula, we have:
F = (5.8 kg) * (6.2 m/s^2) = 35.96 N
Therefore, the net force needed to accelerate a 5800g object at 6.2 m/s^2 is 35.96 Newtons.
