what force is necessary to accelerate a
70kg object at rate of 4.2 m/s2
F = M a
Multiply mass by acceleration. It's Newton's second law.
The answer will have dimensions of newtons
295kg*m/s
To calculate the force necessary to accelerate a 70kg object at a rate of 4.2 m/s^2, you can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
The formula for Newton's second law is:
F = m * a
In this case, the mass (m) is given as 70kg and the acceleration (a) is given as 4.2 m/s^2. Plugging these values into the formula, we can calculate the force:
F = 70kg * 4.2 m/s^2
F = 294 N
Therefore, the force necessary to accelerate a 70kg object at a rate of 4.2 m/s^2 is 294 Newtons.
