Solve question four please :) thank you

Essential formulae FORMULAE to be used Gravitational Force: F = mg (always downward) Normal Force: FN = mg (always positive and is perpendicular to the plane) Frictional Force: Eric = HEN Net Force: ENet = ma OR ENet = Fapp + Eris. Force applied: Fapp = Net - Efric Acceleration: a = ENet/m Coefficient of Friction J (no sign and unit) = Efric/FN 4.) To accelerate a bowling ball at 19.4 [mis*2] forward, 120 [N]-force is 4 points required. What is the MASS, in [kg], of the bowling ball? " Your
