Question

Help me plzzz with these two questions, I need to show my work step by step!

Answer 1

1)
base equation is Force = Mass x Acceleration

so first plug in what we know

20 = Mass x 20

then solve
divide 20/20
1 = the mass of the object

2)
base equation is Force = Mass xAcceleration
plug in what we know
F = 8.5 x 20
multiply
F = 170N
