$1.$ You want to estimate the kinetic energy $($in Joules$)$ of Rhett's Toyota Prius, but you are uncertain about the values you are using to compute it$.$ What is your estimate of the kinetic energy and the uncertainty in your estimate for a $3000$ lb car $($not including you and your stuff$)$ moving $70$ mph$?$ Justify your uncertainty estimates. You won$$t get credit without justifying your assumptions.
