How to calculate acceleration when the force and mass is given

3 monkeys pulling a banana......
one pulling 424 north
one pulling 194 north
and one pulling 400 north

banana is .93 kg

Did you ever consider F = ma ?

For the specific problem you have, add up all the forces. They are all in the same direction, so total force is 1023 somethings
but you need the units of the forces. Newtons? pounds?

a = F/m

so, 1080 / .93 = 1095 m/s^2

No units, no answer. The rules.
