Hi there!
We can use Newton's Second Law:
∑F = net force (N)
m = mass (kg)
a = acceleration (m/s²)
We are given the mass and acceleration, so:
∑F = 20 · 2 = <u>40 N</u>
Answer with Explanation:
We are given that
A.Mass,m=12 kg
Speed,v=1.5m/s
Net force in x direction must be zero
Net force in y direction
Power,P=Fv
Where
B.Substitute the values
