Question

The SI unit for energy is the joule (J), which is equal to the kinetic energy possessed by a 2.00-kg mass moving at 1.00 m/s. Convert this velocity to mph (1 mi=1.609 km). (a) 4.47 x 10^-7 mph (b) 5.79 x 10^6 mph (c) 5.79 mph (d) 0.0373 mph (e) 2.24 mph

Answer 1

e) 2.24 mph

Step-by-step explanation:

• 1 mi = 1.609 Km

⇒v = 1.00 m/s * ( Km / 1000 m ) * ( 3600s / h ) * ( 1 mi / 1.609 Km )

⇒ v = 2.237 mi/h ( mph )
