Find the resultant force that acts on a van with a of mass 2400 kg, if it accelerates at 3.5 m/s2.
a) 800N
b) 685.7 N
c) 0.0015 N
We can use Newton's second law of motion to solve this problem, which states that the net force acting on an object is equal to its mass times its acceleration:
F_net = m * a
where F_net is the net force, m is the mass of the object, and a is its acceleration.
Substituting the given values, we get:
F_net = 2400 kg * 3.5 m/s^2
F_net = 8400 N
Therefore, the resultant force that acts on the van is 8400 N. The answer is not one of the options given.
