293 grams The formula for the wavelength of a massive particle is "" = H/p where "" =Wavelength h = constant of Planck (6.626070040 ® -10^â'34 J*s) p = point (mass by speed) So let's solve for the momentum and from there get the mass "" = H/p ""P = h p = h/"" Substitute the known values and solve p = 6.626070040 ® -10^â'34 J*s/3.45 ® -10^-34 m p = 1.92 J*s/m Since impulse is the product of mass and velocity, we have p = M * V p/V = M To replace again, and resolve. p/V = M 1.92 J*s/m / 6.55 m/s = M 1.92 kg*m/s / 6.55 m/s = M 1.92 kg*m/s / 6.55 m/s = M 0.293 kg = M So the mass is 293 grams
