A 200-kg rock is being pulled upward with an acceleration of 3 m/s2. The net force on the rock is
To determine the net force acting on an object, you 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). Mathematically, this can be represented as:
F = m * a
Given that the mass of the rock is 200 kg and the acceleration is 3 m/s^2, we can substitute these values into the equation to find the net force:
F = 200 kg * 3 m/s^2
F = 600 kg⋅m/s^2
Therefore, the net force on the rock is 600 kg⋅m/s^2.
To find the net force on an object, you can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
Given:
Mass of the rock (m) = 200 kg
Acceleration (a) = 3 m/s^2
Formula:
Net force (Fnet) = mass (m) x acceleration (a)
Substituting the given values into the formula:
Fnet = 200 kg x 3 m/s^2
Calculating the net force:
Fnet = 600 N
Therefore, the net force acting on the rock is 600 Newtons.
