The force on an object is 370N.
What is Newton's second law of motion?
Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it.
Newton's second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a).
According to the question,
m = 148 kg , v = 85m/s , u = 35 m/s
[tex]a = \frac{v - u}{t}[/tex]
a = [tex]\frac{85m/s- 35m/s}{20s}[/tex]
a= 2.5 m/s²
By computing the values,
F=ma
F = 148×2.5
F = 370N
Therefore,
370N is the force on an object.
