Answer:
i assume the system is in equilibrium
Explanation:
(W_p-T)(2)+W_b(2.5)= T(sin 45 degrees)(5)
T(((sin 45 degrees)(5)) + 2) = (W_p)(2) + W_b(2.5)= T(5.5355)
Answer:
KE = 1/2mv^2
KE = 1/2(24)(3^2)
KE = 12(9)
KE = 108 J
Let me know if this helps!
Answer:
To show that magnets repel, you must place the strong and weak magnets to another magnet with their poles being both south or both north facing eachother.
To show they attract, place opposite poles near eachother.
A=vf-vi/tf-ti
a= velocity final-velocity initial / time final-time initial
a= 6 m/s - 3 m/s divided by 8 s - 0s
a= 2 m/s / 8 m/s
a= 1/4 m/s^2
