Question Translation:
SOLUTION :
1.
F - T = M a
=> a = (F - T) / M (ANSWER)
If M is doubled, a will be halved if F and T remain unchanged. (ANSWER).
2.
Under freefall :
____
I I
I ___ I
I
V
W = Mg
Mg = Ma
=> a = g (ANSWER)
If mass is doubled, a remains same and equal to g as relationship of a nd g is independent of M. (ANSWER)
Question Translation: On a car of mass M, two forces act as shown in the figure above. Find an expression for the acceleration of the car in terms of T, F, and M. What happens to the acceleration if...
Question Translation: On a car of mass M, two forces act as shown in the figure above. Find an expression for the acceleration of the car in terms of T, F, and M. What happens to the acceleration if we double the mass of the car? An object of mass M is in free fall (the only force on the object is its weight). Make a force diagram for this case. Use Newton's second law to calculate the acceleration of...
Only 2 and 5 2. Three spheres of 5.00 kg each are separated by the distances d1 and d2 as shown in the figure. Calculate the force of attraction, in vectorial representation, if the distances are d1 = 0.300 -? -? m and d2 = 0.400m. Ans: ? = ?.?? × ??^-8 ?? + ?.?? × 10^-6 5. At what altitude on the surface of the Earth, the acceleration of gravity would have a value of 4.9 m / s2?...
A horizontal bar is used to hold an object of m kg between two walls, as shown in the figure. The equally exerted forces of the bar against the walls can be changed by adjusting the length from the bar. The system is only sustained by friction between the ends of the bar and the walls. The coefficient Static friction between these two is ms. Find the value of the forces F that guarantee the equilibrium of the system. with...
A point mass moves without friction on the inside of a surface of revolution z=f(r) whose axis of symmetry is along a gravitational field a)Find the condition for a stationary circular orbit of radius and show that It is stable or unstable under small impulses along a transverse surface to the direction of movement according to whether it is positive or negative. For a stable orbit, find the frequency ω of small oscillations around the balance setting. Original Question(in spanish)...
