a car is traveling with a velocity of 40 mls and has a mass of 1120 kg. the car has energy calculate it
Answer (1)
SOLUTION:Step 1: List the given values.[tex]\begin{aligned} & m = \text{1120 kg} \\ & v = \text{40 m/s} \end{aligned}[/tex]Step 2: Calculate the kinetic energy.[tex]\begin{aligned} KE & = \frac{1}{2}mv^2 \\ & = \frac{1}{2}(\text{1120 kg})(\text{40 m/s})^2 \\ & = \boxed{\text{896,000 J}} \end{aligned}[/tex]Hence, the kinetic energy of the car is 896,000 J.
