A 10 m long uniform beam weighing 100 N is supported by two ropes at the ends. If a 400 N person sits at 2.0 m from one end of t

Naddik [55]

Answer:

T1 = 130N, T2 = 370N

Explanation:

In order for the system to be at rest, the sum of all forces must be zero and the torque around a point on the beam must be zero.

1. forces:

Let tension in rope 1 be T1 and in rope 2 be T2:

ma = T1 + T2 - 100N - 400N = 0

(1) T1 + T2 = 500N

2. torque around the center point of the beam:

τ = r x F = 5*T1 + 3*400N - 5*T2 = 0

(2) T1 - T2 = -240N

Solving both equations:

T1 = 130N

T2 = 370N

A satellite at a particular point along an elliptical orbit has a gravitational potential energy of 4700 MJ with respect to Eart

erastovalidia [21]

during satellite motion we know that total energy is always conserved

so here we will have

$KE_i + PE_i = KE_f + PE_f$

here we know that

$KE_i = 4800 MJ$

$PE_i = 4700 MJ$

now at other position

$PE_f = 6000 MJ$

now from above equation we have

$4800 +4700 = 6000 + KE$

now we have

$9500 = 6000 + KE$

$KE = 9500 - 6000 = 3500 MJ$

so its kinetic energy will be 3500 MJ
