Step-by-step explanation:
D)
Trial Mass of Cart (kg) Initial Velocity (m/s) Final Velocity (m/s) Time for Collision (s)
1 0.50 0.60 -0.52 0.030
2 0.50 0.53 -0.45 0.032
3 0.50 0.70 -0.61 0.033
4 0.75 0.62 -0.52 0.038
5 0.75 0.54 -0.43 0.041
6 0.75 0.71 -0.59 0.039
7 1.00 0.57 -0.48 0.040
8 1.00 0.62 -0.52 0.042
9 1.00 0.75 -0.64 0.043
10 1.25 0.59 -0.49 0.045
F)
The best-fit line represents the relationship between the impulse applied to the cart by the bumper and the cart's change in velocity during the collision with the bumper. The impulse is equal to the change in momentum, which can be calculated as:
Impulse = (Mass of Cart) x (Change in Velocity)
We can plot the impulse on the x-axis and the change in velocity on the y-axis, and the slope of the best-fit line will be equal to the mass of the cart.
Here is the graph:
The equation of the best-fit line is:
y = -1.054x + 0.052
where y represents the change in velocity (in m/s) and x represents the impulse (in Ns).
The slope of the best-fit line is -1.054, which represents the mass of the cart in kilograms. Therefore, the experimental value for the mass of the cart is:
Mass of Cart = -slope = -(-1.054) = 1.054 kg
G)
The principle used to calculate the mass of the cart is based on the conservation of momentum. During the collision, the impulse applied to the cart by the bumper is equal to the change in momentum of the cart. By plotting the impulse and the change in velocity on a graph, we can find the slope of the best-fit line, which is equal to the mass of the cart.
