What is the kinetic energy of a 1.4 kg discus with a speed of 22.5 m/s?

354.375 J

Step-by-step explanation:

The formula to find kinetic energy is:

× mass ×

Mass = 1.4 kg

Speed = 22.5m/s

So the kinetic energy will be:

× 1.4 ×

= × 1.4 × 506.25

Kinetic energy= 354.375 joules

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
