What is the mass of the rocket?

Question

A constant net force of 1360 N gives a toy rocket an acceleration of 2.4 m/s². What is the mass of the rocket?
 ____ kg

Answer 1

Write down what is given:

 

F = 1360 kg m/s²

a = 2.4 m/s²

m = ?

 

Newton's 2nd law equation is

 

F = ma 

 

m = F/a

m = (1360 kg m/s²) / (2.4 m/s²)

m = 566.67 kg
