Question

suppose you and a classmate push a cart loaded with bricks to demonstrate force. you apply a force of 500 N, and the cart accelerates at a rate of 5 m/s2. What mass does the cart have?

Answer 1

Solution

- The formula for calculating the force acting on an object is:

$\begin{gathered} F=ma \\ where, \\ m=\text{ Mass of the object} \\ a=\text{ Acceleration of the object} \end{gathered}$

- The force applied to the cart is 500N and it moves with an acceleration of 5m/s².

- Thus, we can find the mass of the object using the formula above as follows:

$\begin{gathered} 500=m\times5 \\ \text{ Divide both sides by 5} \\ \\ m=\frac{500}{5} \\ \\ \therefore m=100kg \end{gathered}$

Final Answer

The mass of the cart is 100kg
