A 13-kg sled is moving at a speed of 3.0 m/s. At which of the following speed will the sled have twice as much kinetic energy?
<span>4.2 m/s</span>
5.972 × 10^24 kg
it is the weight of earth
hope it is helpful to you
I believe the answer is c but I’m not 100% sure
Ok so if each side is 4.53 cm, we can multiply 4.53 x 4.53 x 4.53 to get the volume (since v= l x w x h). Density equals mass/volume, so
519 g/4.53 cm
114.57 g/cm^3 (since none of the units cancel)
