a. 12.5 kg
step-by-step explanation:
f = ma
so
m = f/a = (2500 n)/(200 m/s²) = 12.5 kg
1 n = 1 kg·m/s²
1/3
step-by-step explanation:
to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
