Answer:

25/32 kg

Step-by-step explanation:

The kinetic energy K of a body in motion measured in joules is given as

K = 1/2 mV^2

Where n is the mass in kg and V is the speed in m/s

Hence given that K is 25J and speed V is 8 m/s,

25 =1/2 * m * 8^2

25 = m *32

Divide both sides by 32

m = 25/32 kg
