1. m = 1 kg , a = 10 m/s² , F = ?
F = ma
F = (1 kg)(10 m/s²)
F = 10 kg•m/s²
F = 10 N
2. F = 20 N, a = 10 m/s², m = ?
m = F/a
m = 20 N / 10 m/s²
m = 20 kg•m/s² / 10 m/s²
m = 2 kg
3. m = 4 kg, a = 10 m/s², F = ?
F = ma
F = (4 kg)(10 m/s²)
F = 40 kg•m/s²
F = 40 N
4. m = 8 kg, a = 10 m/s², F = ?
F = ma
F = (8 kg)(10 m/s²)
F = 80 kg•m/s²
F = 80 N
