What is the force of an 18kg object accelerating at 4m/a squared?
F=ma
3. (a) How much work is done in raising a 50.0 kg crate a distance of 3.5 m above a storeroom floor? (b) What is the change of potential energy as a result of this move? (c) How much kinetic energy will the crate have as it falls and hits the floor?
To calculate the force exerted on an object, you can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
In this case, you have an object with a mass of 18 kg and an acceleration of 4 m/s^2. To find the force, you can use the formula:
F = m * a
Substituting the given values, you get:
F = 18 kg * 4 m/s^2
Multiplying 18 kg by 4 m/s^2, the force exerted on the object is:
F = 72 Newtons
Therefore, the force exerted on the 18 kg object accelerating at 4 m/s^2 is 72 Newtons.
