Answer:
a) 156960 N/m
b) Yes the player can play on the team.
Explanation:
F = Force
a = Acceleration due to gravity = 9.81 m/s²
m = Mass
k = Spring constant
x = Deformation length of spring
F = ma
From Hooke's law

The effective spring constant is 156960 N/m
When x = 0.48 cm = 0.0048 m

The mass of the player is 76.8 kg which is less than the required mass limit of the players' which is 85 kg. So, the player is eligible to play.
Answer:
0.2s
force = change in momentum/ time
time = change in momentum/time
Explanation:
first, let's find the change in momentum
pf-pi
5×(-2) - 5× 2
-20kgm/s = 20kgm/s(by changing the direction of whole system)
time = change in momentum/time
20/100
<u> 0.2s</u>
Since the current is inversely propotional to its resistance, when the voltage is doubled the current will be one-half
Answer:
Hey there!
They used math to explain their observations, for example, Newton is famous for his three laws, and universal laws of gravitation.
Let me know if this helps :)
