Question

Hello I could really use help with this question please!

Answer 1

Given:

The velocity of the car is v = 2 m/s when the time is 1.3 s

The mass of the car is

`m_(car)=\text{ 1.5 kg}`

To find the kinetic energy when the time is 1.3 s

Step-by-step explanation:

The kinetic energy can be calculated by the formula

`K.E.\text{ =}(1)/(2)m_(car)v^2`

On substituting the values, the kinetic energy will be

`\begin{gathered} K.E.\text{ =}(1)/(2)*1.5*(2)^2 \\ =\text{ 3 J} \end{gathered}`

Final Answer: The kinetic energy will be 3 J when the time is 1.3 s.
