Question

What is the acceleration of a 45 kg mass pushed with 15 N of force? What is the acceleration if the force changes to 25 N? What if the mass changes to 70 kg?

Answer 1

a = .33m/s^2

a=.55m/s^2

don't understand the last question

Answer 2

A= 0.33m/s

A=0.56m/s

A=0.21m/s

A= 0.35m/s

Step-by-step explanation:

To calculate acceleration, you will use the formulae,

Force=mass ×acceleration.

F=MA.

If the force is 15N, Mass is 45g , acceleration ?

15=45 × a

15=45a.

Divide through by 45 to get a

a=15/45

Acceleration is 0.33m/s

B) acceleration if forces changes to 25N.

F=MA

F= 25, M= 45 a=?

25=45 × a

25= 45a

Divide through by 45 to get a.

a= 25/45

Acceleration is 0.56m/s

C) Acceleration if mass changes to 70N.

F= MA

15= 70 × a.

15= 70a

Divide through by 70

15/70= a

Acceleration is 0.21m/s

If the Force is 25N, Mass is 70kg, acceleration will be.

F=MA

25=70 × a

25=70a

Acceleration= 25/70

Acceleration is 0.35m/s
