Answer:
To avoid slipping while playing badminton or to increase friction between the shoes and the badminton court or to enhance the grip.
Explanation:
As the question is general so I will try answer it generally.
As badminton court is usually slippery and flat with no or very little friction and while playing badminton, players have to move very fast from place to place.
So, in order to effectively move faster to take the difficult shots with accuracy badminton players increase the friction between their shoes and the badminton court by shuffling resin to their shoes. It helps to enhance the grip.
Answer:
Explanation:
Given
Inclination 
Distance of landing point 
Considering athlete to be an Projectile
range of projectile is given by
where u=launch velocity
(b)If u is increased by 8% then
new velocity is 
Use the formula:
E = (1/2) * m * v ^2
For unit consistency, make sure that:
E energy is in joules (J)
m mass is in kilograms (kg)
v velocity is in meters per second (m/s)
So, substituting to the equation:
14= (1/2) * (17) * v^2
By algebraic manipulation, we derive:
v = (2*14/17)^0.5
v = 1.2834 m/s
