Answer to Question #165889 in Physics for Azucena Vazquez

Question

An object with mass 818 grams is thrown at an angle with initial speed 2.45 m/s on a level field. 

What is its kinetic energy at the moment just before it lands?

Your answer should be in Joules, but you don't need to write the unit, just the number. 

Answer 1

$$K=0.5mv^2\\K=0.5(0.818)(2.45)^2=2.46\ J$$
