Jada is driving her 1395-kg Prius at 21.7 m/s.
Calculate the kinetic energy of the Prius.
If Jada drives with one-half the speed, what would be the kinetic energy of her Prius?
A bicycle has a kinetic energy of 150 Joules.
What kinetic energy would the bicycle have if it had twice the mass and was moving at the same speed?
KE
What kinetic energy would the bicycle have if it had the same mass and was moving with twice the speed?
What kinetic energy would the bicycle have if it had one-half the mass and was moving with twice the speed?
What kinetic energy would the bicycle have if it had the same mass and was moving with one-half the speed?
What kinetic energy would the object have if it had three times the mass and was moving with one-half the speed?
