Answer:
601.92 N
Step-by-step explanation:
Using Newton's equation of kinematics,
F = ma .......................... Equation 1
Where F = force, m = mass of the box, a = acceleration of the box.
we can look for acceleration using the equation of motion
s = ut+1/2at²................. Equation 2
Where s = distance, u = initial velocity, and t = time.
Given: s = 58 m, t = 4.3 s, u = 0 m/s (at rest)
substitute into equation 2
58 = 0(4.3)+1/2(a)(4.3²)
58 = 9.245a
a = 58/9.245
a = 6.27 m/s²
Also given: m = 96 kg
Substitute into equation 1
F = 96(6.27)
F = 601.92 N
