An object moving with a speed of 35 m/s and has a kinetic energy of 1500 J, what's the Mass

Hello! To find mass, you have to do force/acceleration. In this case, we would do 1500/35. When you do that, you would get a bunch of numbers on a calculator, but it would be 42.86 when rounded to the nearest hundredth. The mass of the object is 42.86.
