mass of object is 50mg so we need to convert to kg, the standard unit.divide by 1000 to convert mg to grams then divide by 1000 again to convert grams to kg. i got 50 * 10^-6 kg.
next identify that the velocity is 250 m/s
m = 50 * 10^-6 kg
v = 250 m/s
an objects momentum is the direct relationship between its mass and velocity
p = m*v or (50*10^-6kg) * (250 m/s)
kinetic energy is obtained from the direct integration of momentum with respect to time
k = (1/2)*m*(v^2) 0r (1/2)*(50*10^-6kg) * (250 m/s)^2
