A sledgehammer has a mass of 4 kilograms. What net force, to the nearest whole newton, will a person need to apply to accelerate the sledgehammer at a rate of 2.5 m/s2?
Using the formula F = ma, where F is the net force, m is the mass, and a is the acceleration, we can calculate the net force required.
F = (4 kg)(2.5 m/s^2)
F = 10 N
Therefore, a person will need to apply a net force of 10 Newtons to accelerate the sledgehammer at a rate of 2.5 m/s^2.
