Question

The amateur boxers, use larger and more padded gloves than professional boxers. The amateur boxers are more protected from injury because:

• A. The larger glove exerts a larger impulse on the boxer
• B. The larger glove exerts a larger force on the boxer
• C. The larger glove exerts more energy on the boxer
• D. The larger glove increases time of impact on the boxer
• E. The larger glove increases the power exerted on the boxer

Answer 1

The correct option is D The larger glove increases time of impact on the boxer

We have impulse $\overrightarrow{I}=\overrightarrow{F}\times t={\overrightarrow{p}}_2-{\overrightarrow{p}}_1$

when a boxer hits another boxer , change in momentum remains constant therefore product of force and time should be constant .we can decrease the force by increasing time of impact so boxer uses larger gloves to increase the time of impact thus decreases the force and avoids from injury.
