A mass of 3 tonnes undergoes an acceleration of 10 m/s2. What is the net force, in newtons(N) that produced this acceleration?
Question
A mass of 3 tonnes undergoes an acceleration of 10 m/s². What is the net force, in newtons (N) that produced this acceleration?
Solution
To find the net force, we can use Newton's second law of motion, which states that Force = mass x acceleration.
Step 1: Convert the mass from tonnes to kilograms, because the standard unit of mass in physics is the kilogram. 1 tonne is equal to 1000 kilograms, so 3 tonnes is equal to 3000 kilograms.
Step 2: Multiply the mass by the acceleration to find the force.
Force = mass x acceleration = 3000 kg x 10 m/s² = 30000 N
So, the net force that produced this acceleration is 30000 Newtons.
