The force require to stop the second object is greater because it has bigger momentum when compared to the first object.
The given parameters;
- mass of the first object, m₁ = 8 kg
- speed of the first object, u₁ = 0.2 m/s
- mass of the second object, m₁ = 4 kg
- speed of the second object, u₂ = 1 m/s
The force required to stop each object in the given time is determined by applying Newton's second law of motion as shown below;
[tex]F = ma = \frac{mv}{t} \\\\F_1 = \frac{8 \times 0.2}{10} \\\\F_1 = 0.16\ N[/tex]
For the second object;
[tex]F_2 = \frac{4 \times 1}{10} \\\\F_2 = 0.4 \ N[/tex]
Thus, the force require to stop the second object is greater because it has bigger momentum when compared to the first object.
