Problem 1:
Given:
F = 30 N
m = 88 kg
Required:
a
Solution:
F = ma
---------------------------------------------------------
Problem 2:
Given:
m = 1,750 kg
a = 5 m/s²
Required:
F
Solution:
F = ma
F = (1,750 kg)(5 m/s²)
---------------------------------------------------------
Problem 3:
Given:
F = 12.5 N
a = 7.5 m/s²
Required:
m
Solution:
F = ma
