7)
mass , m = 7 kg
acceleration , a = 7 m/s^2
the net force , F = m * a
F = 7 * 7 N = 49 N
8)
the net force , Fn = 9 N - 3 N = 6 N upwards
the acceleration , a = Fn /m
a = 6 /4 m/s^2 upwards = 1.5 m/s^2 upwards
9)
the net force , Fn = 400 N - 300 N = 100 N rightwards
the acceleration , a = Fn /m
a = 100 /10 m/s^2 rightwards = 10 m/s^2 rightwards
