How much force is needed to make a 90-kg object accelerate at a rate of 3 m/s^2?
270 N
93 N
60 N
30 N
just help me pls T~T my name says exactly what i am ._.
HHHHHHHHHHHEEEEEEEEEEELLLLLLLLPPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!
F = ma
so plug in your numbers
To calculate the force needed to make an object accelerate, you can use Newton's second law of motion, which states that force (F) equals mass (m) multiplied by acceleration (a). In this case, the mass (m) is given as 90 kg, and the acceleration (a) is given as 3 m/s^2.
So, using the formula F = m * a, you can substitute the given values to find the force (F).
F = (90 kg) * (3 m/s^2)
F = 270 N
Therefore, the correct answer is 270 N.
