Question

A net force of 12.0 N causes an object to increase its speed from 15.0 m/s to 18.0 m/s during a 2.0 second interval. What is the mass of the object?

Answer 1

Answer:

Mass of object = 8kg

Explanation:

• Since a= change in v/ change in t, a= (18-16)/2

= 1.5

• And F=ma
• Force =12
• a= 1.5
• m=?

You can now solve for your unknown value of mass.
