In this experiment, the motion of a fan cart with a mass of 480g was measured as it accelerated from rest, along a horizontal track. These results were calculated from data collected by LoggerPRO.

Trial 1 Trial 2 Trial 3

Acceleration from x-t graph (m/s²) 0.642 0.622 0.651

Acceleration from v-t graph (m/s²) 0.618 0.664 0.604

A new experiment will be run, with these changes:

A mass of 120g is added to the cart (we experimented with different masses last week), and
The track is inclined at 4.5° (we experimented with carts on inclines earlier in the course)

Will the fan cause the same cart to accelerate up the incline, down the incline, or will the cart remain at rest? Show your calculations, and explain fully in words.

A fan exerts a force of 10 N on a frictionless cart of mass 250 g, accelerating the cart from rest over a distance of 0.5 m. The same fan is then used to accelerate a 500 g cart from rest over the same distance. Select ALL statements below that are TRUE about this situation: A) The energy transferred to both carts is different. B) The work done by the fan in both cases is the same. C) The final...

4. Two carts collide and stick together in a lab experiment. Cart 1 has a mass of 550 g and a speed before the collision of 2.5 m/s. Cart 2 has a mass of 320 g and a speed of -4.1 m/s. Consider the 2 carts to be the system. A. What is the total momentum of the system before the collision? B. What is the velocity of the 2 carts after the collision? C. If the collision takes 0.15s,...

How is the motion of the mass on the spring similar to the motion of the bob? How is it different? Then, why does the period of a pendulum not depend on mass but it does for the spring? Explain carefully. Simple harmonic motion is used to describe physics most complex theories. How could something so simple describe the most complex

A patient's energy expenditure is measured using indirect calorimetry with a metabolic cart in a rested state and they have not eaten for 2 days other than clear liquids (clear liquids have CHO and no other source of kcalories). The RQ is 0.72 and the REE is 1400 kcal extrapolated for 24 hours. What does the RQ mean and how many kcalories does this person need, i.e. what is their TEE?

Reaction Run 3 Measured Mass of NaHCO3 = 0.99 g, Measured Mass of H3C6H5O7 = 1.52 g, Measured Mass of CO2 = 0.48 g. Determine the limiting reactant in the reaction run 3. Describe your reasoning. (10 points) Calculate the amount (in g) of carbon dioxide from the amount of the limiting reactant that you used in the reaction run 3. The amount that you calculate is called the theoretical yield. Show all your work. (10 points) The measured mass...

At a major food production facility, a cart of bananas with a mass of 200kg is at the top of a 10m high hill, moving with a speed of 6m/s. At the end of the production line is a segment where brakes are applied (uk = 0.4; D = 8m), and then the cart runs into a giant stopping spring (K = 10,000 N/m; total length = 4m). a. Draw a FBD of the cart while in contact with the...

A frictionless cart of mass ? = 4.00 kg has a shape of a ramp with an incline angle ? = 60.0°. The ramp is pulled by a constant horizontal force ? = 15.0 N. Another frictionless cart of mass? = 2.00 kg can roll along the ramp and is attached to the top of the ramp at point ? by a spring of constant ? = 300. N/m. The spring is free to pivot without friction around point ?....

I did an experiment in which a cart on wheels is getting pulled by a pulley hanging off the surface. The pulley has a 50g hanger which causes the motion. The cart is 300g and then in different trials added one 50g weight, two, three, and then four. The slope was 0 degrees. My question is: Describe (and show with pictures) what forces change for each of the different configurations used.
