The cart with the greatest change in speed is the cart with a mass of 75 Kg
Acceleration is defined as the change in velocity of an object with time. Also, acceleration is related to the force and mass according to the following equation:
Acceleration (a) = Force (F) / mass (m)
<h3>a = F / m</h3>
To answer the question, we shall determine the acceleration of each cart.
<h3>For cart of mass 75 kg</h3>
- Mass (m) = 75 Kg
- Force (F) = 200 N
- Acceleration (a) =?
a = F / m
a = 200 / 75
<h3>a = 2.67 m/s²</h3>
<h3>For cart of mass 125 kg</h3>
- Mass (m) = 125 Kg
- Force (F) = 200 N
- Acceleration (a) =?
a = F / m
a = 200 / 125
<h3>a = 1.6 m/s²</h3>
<h3>For cart of mass 350 kg</h3>
- Mass (m) = 350 Kg
- Force (F) = 200 N
- Acceleration (a) =?
a = F / m
a = 200 / 350
<h3>a = 0.57 m/s²</h3>
<h3>For cart of mass 450 kg</h3>
- Mass (m) = 450 Kg
- Force (F) = 200 N
- Acceleration (a) =?
a = F / m
a = 200 / 450
<h3>a = 0.44 m/s²</h3>
From the above illustrations, we can see that the cart with a mass of 75 K has the greatest change in speed (i.e 2.67 m/s²)
