Use the KE and GPE equations to solve for speed or height depending on the situation.

A 1,000-kg car has 50,000 joules of kinetic energy. What is its speed?
(please show work)

Kinetic energy = 0.5*mass*velocity²  
0.5*1000*v²=50,000
v²=50,000/(0.5*1000)

v=√(50,000/(0.5*1000))
v=√100=
v=10m/s²

Answer:

½mv²= KE  

½(1000)?²= 50000

500*?²= 50000

/500            /500

? ²=100

Square root  

?= 10

10 m/s is you answer
