25.19 Assuming that drag is proportional to the square of velocity, we can model the velocity of a falling object like a parachutist with the following differential equation: dv dt where v is velocity (m/s), 1 = time (s), g is the acceleration due to gravity (9.81 m/s), c = a second-order drag coefficient (kg/m). and m 90-kg object with a drag coefficient of 0.225...

2, When you divide the total distance and total time for a trip, you calculate a(n) average acceleration instantaneous speed average speed non-uniform speed constant speed 3. A heavy object and a light object are dropped from rest at the same time in a vacuum. The heavier object will reach the ground It depends on the shape of the object at the same time as the lighter object It depends on the mass of the object after the lighter object...

from the graph in Figure 2. 2 kg 100 N/m Foooo A student is conducting an experiment to analyze the mechanical energy of a block-spring system. The student places a block of mass 2kg on a horizontal surface and attaches the block to a horizontal spring of negligible mass and spring constant 100N/m, as shown in the figure. There is negligible friction between the block and the horizontal surface. The other end of the spring is attached to a wall....

please help with #7 and question 6 (the last question)
3. Rescale the axes if necessary to see all of the graphs. Answer the following questions: a. At the instant the push ends, what does the force equal? F= b. At the instant the push ends, what does the acceleration equal? a= c. At the instant the push ends, what can you say about the speed of the cart? Look carefully at the graphs on the computer monitor. 4. Use...
