Answer:
F = 1.099N
Explanation:
See the attachment below.
The player that possess the best ball handling skills and usually handles
the ball often is referred to as the point guard.
Point guards in basketball are referred to as the players who have certain
characteristics such as speed ,an excellent ball handling skills and
leadership qualities.
Point guards is similar to the creative midfielder in soccer which helps to
dictate play and create chances for other team mates which is why they
handle the ball often.

I believe the answer is B.
Answer:
300 Pascal
Explanation:
Given
weight or force (F) = 6000 N
area (A) = 20 m²
pressure (p) = ?
we know
the force acting normally per unit area is pressure. So
P = F / A
= 6000 / 20
= 300 Pascal
Hope it will help :)
Answer:
Explanation:
Impulse of reaction force of floor = change in momentum
Velocity of impact = √ 2gh₁
= √ 2 x 9.8 x 1.5 = 5.4 m /s.
velocity of rebound = √2gh₂
= √ 2x 9.8 x 1
= 4.427 m / s.
Initial momentum = .050 x 5.4 = .27 kg m/s
Final momentum = .05 x 4.427 = .22 kg.m/s
change in momentum = .27 - .22 = .05 kg m/s
Impulse = .05 kg m /s
Impulse = force x time
force = impulse / time
.05 / .015 = 3.33 N.
kinetic energy = 1/2 m v²
Initial kinetic energy = 1/2 x .05 x 5.4²
= 0.729 J
Final Kinetic Energy =1/2 x .05 x 4.427²
= 0.489 J
Change in Kinetic energy =0 .24 J
Lost kinetic energy is due to conversion of energy into sound light etc.
