A car with mass 450 kg has a kinetic energy of 16,256 J. What is the speed of the car?A.11.2 m/sB.1.2 m/sC.8.5 m/sD.5.9 m/sSUBMITarrow_backPREVIOUS
Question
Solution 1
The kinetic energy (KE) of an object can be calculated using the formula:
KE = 1/2 * m * v^2
where m is the mass of the object and v is its velocity. We can rearrange this formula to solve for v:
v = sqrt((2*KE)/m)
Substituting the given values:
v = sqrt((2*16256 J)/450 kg)
v = sqrt(72504/450) Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
