If a cart is initially travelling at 3.5 m/s, and has a mass of 200g, what is it's kinetic energy (LEAVE OUT units of J)?
0.5*0.2KG*3.5^2=1.225 J
To calculate the kinetic energy of an object, you can use the equation:
Kinetic Energy = (1/2) * mass * velocity^2
First, convert the mass of the cart to kilograms by dividing by 1000:
mass = 200g / 1000 = 0.2 kg
Next, substitute the given values into the equation:
Kinetic Energy = (1/2) * 0.2 kg * (3.5 m/s)^2
Simplify the equation:
Kinetic Energy = 0.5 * 0.2 kg * 12.25 m^2/s^2
Multiply the values:
Kinetic Energy = 1.225 J
Therefore, the kinetic energy of the cart is 1.225 Joules.
