a sledgehammer has a mass of 3.5 kilograms. what net force, to the nearest whole newton, will a person need to apply to accelerate the sledgehammer at a rate of 4.0m/s²?
Answer
Explanation:
Step1: Recall Newton's second - law
$F = ma$
Step2: Substitute given values
$m = 3.5\ kg$, $a=4.0\ m/s^{2}$, so $F=(3.5)\times(4.0)$
Step3: Calculate the force
$F = 14\ N$
Answer:
14
