a. W = m g, so m = W/g

Divide the weight (in Newtons)by the acceleration of gravity (9.8 m/s^2) and you will get the mass in kilograms

b. F = ma, so a = F/m

Use the m from part (a)

The answer will depend upon whether the 69 N "applied" force F includes the weight. If it doesn't, the ball will still fall downwards, in reposnse to a net force of 69 -95 = -26 N
