Answer:
Given
Mass m = 70 kg
Acceleration a = 5 m/s²
To determine
Force F = ?
Using the formula
F = ma
substituting m = 70 kg and a = 5 m/s²
F = 70 × 5
F = 350 N
Therefore, the sprinter is exterting a 350 N force.
Question No 7
Given
Mass m = 80 kg
Acceleration a = 10 m/s²
To determine
Force F = ?
Using the formula
F = ma
substituting m = 80 kg and a = 10 m/s²
F = 80 × 10
F = 800 N
Therefore, the sprinter is exterting a 800 N force.
