Question

A football of mass 0. 430 kg is initially at rest. After being kicked, the football moves with a speed of 5. 00 m/s. What was the magnitude of the impulse applied to the football?.

Answer 1

• 2.15 kg m/s

Step-by-step explanation:

Given :-

A football of mass 0. 430 kg is initially at rest. After being kicked, the football moves with a speed of 5. 00 m/s.

Mass of football = 0.430 kg

Initial velocity = 0 m/s

Final velocity = 5 m/s

Need to Find :-

• Impulse

Required solution :-

Formula used for calculation of Impulse,

• J = mv

Here,

J = Impulse

m = mass

v = Final Velocity - Initial velocity

Plugging the Values,

• v = (5m/s - 0m/s)
• v = 5m/s

➥ J = 0.430kg × 5m/s

➥ J = 2.15 kg m/s

Hence, The impulse generated is 2.15 kg m/s
