Answer:

m = 327.07 kg

Step-by-step explanation:

Given that,

Kinetic energy of a motorcycle, E = 57800 J

Velocity of the motorcycle, v = 18.8 m/s

We need to find the mass of the motorcycle. The kinetic energy of an object is given by :


E=(1)/(2)mv^2

m is mass


m=(2E)/(v^2)\\\\m=(2* 57800 )/((18.8)^2)\\\\m=327.07\ kg

So, the mass of the motorcycle is 327.07 kg.
