Total Current = 2 Amps
Req total = 60 ohms
Current on EF mesh = 1/3 Amp
Current on 24 ohms resistor = 1/6 Amp

Voltage on the 40ohms resistor is lefting.

An 80.0-kg man jumps from a height of 2.50 m onto a platform mounted on springs. As the springs compress, he pushes the platform
frosja888 [35]

Answer:

6.16 m/s

0.0105 m

Explanation:

Let the ground 0 for potential reference be at where the spring is compress 0.24 m. The the man would jump from a height h = 2.5 + 0.24 = 2.74 m from it. We can apply the law of energy conservation knowing that as the man jumps, his potential energy converts to kinetic energy, then finally to elastic energy:

E_p = E_e

mgh = kx^2/2

where m = 80 kg is the man mass, g = 9.81 m/s2 is the gravitational acceleration, h = 2.74 m is the potential distance he travels, k N/m is the spring constant and x = 0.24 is the distance it compresses

80*9.81*2.74 = k0.24^2/2

2150.352 = 0.0288k

k = 74665 N/m

Similarly at the position where it compresses by 0.12 m, it's 0.24 - 0.12 = 0.12 m far from ground 0.

E_p = E_{e2} + E_k + E_{p2}

mgh = kx_2^2 + mv^2/2 + mgh_2

2150.352 = 74665*0.12^2/2 + 80v^2/2 + 80*9.81*0.12

2150.352 = 537.588 + 40v^2 + 94.176

40v^2 = 1518.588

v^2 = 37.9647

v = \sqrt{37.9647} = 6.16 m/s

When he steps gently, then his gravity force would equal to his spring force

mg = kx_3

x_3 = mg/k = 80*9.81/74665 = 0.0105m

Why does green light slow down more than orange light does when passing through an object?
jeka94
Because when a white light goes through a clear object like the glass pyrimide it divides into the different color lights the different color lights travel in different speeds like the red light traveles faster that the purple light thats why on a rainbow the red is on the top and purple is on the bottom
