A cart of mass m is pulled along a level dynamics track as shown above. A force sensor is attached to the cart with a string and

mart [117]

Answer:

<u>See the picture attached with the drawing of the forces.</u>

Explanation:

Find the figures with the question and the answer attached.

The answer shows the free body diagram with four arrows starting on, and pointing way from, the dot.

The red vertical upward arrow, labeled $F_N$ , represents the normal force, which is the force exerted by the ground on the cart.

The red vertical downward arrow, labeled $F_g$ , represents the gravity force (weight), which is the pull that the Earth exerts of the cart.

Both vertical arrows are of the same side because the normal force and the weight are balanced (since there is not vertical acceleration).

The blue horizontal arrow pointing to the right, labeled $F_h$ , represents the horizontal pulling force exerted by the hand.

The blue horizontal arrow pointing to the left, labeled $F_f$ , represents the frictional force which is not neglicible.

Since the cart is accelerating in the positive direction, toward the right,

$F_h>F_f$ and the arrow to the right is larger than the arrow to the left.

President Franklin Roosevelt had issues with the Supreme Court when it found some of his programs unconstitutional. In an attemp

Lunna [17]

Answer: the first election returns reached his family estate in Hyde Park, New York, on a November night in 1936, Franklin Delano Roosevelt leaned back in his wheelchair, his signature cigarette holder at a cocky angle, blew a smoke ring and cried “Wow!” His huge margin in New Haven signaled that he was being swept into a second term in the White House with the largest popular vote in history at the time and the best showing in the electoral college since James Monroe ran unopposed in 1820.

The outpouring of millions of ballots for the Democratic ticket reflected the enormous admiration for what FDR had achieved in less than four years. He had been inaugurated in March 1933 during perilous times—one-third of the workforce jobless, industry all but paralyzed, farmers desperate, most of the banks shut down—and in his first 100 days he had put through a series of measures that lifted the nation’s spirits. In 1933 workers and businessmen marched in spectacular parades to demonstrate their support for the National Recovery Administration (NRA), Roosevelt’s agency for industrial mobilization, symbolized by its emblem, the blue eagle. Farmers were grateful for government subsidies dispensed by the newly created Agricultural Adjustment Administration
