Step-by-step explanation:

Given that,

Mass of Ella is 56 kg and mass of Tyrone is 68 kg.

Position of Ella is 1.5 m on the ramp.

Potential energy of an object is given by :

P = mgh

It is directly proportional to the position of an object.

If Tyrone stands at the top of ramp at more height than Ella, it will have more potential energy. Hence, the correct option is (d) "If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's."

Y_Kistochka [10]

Answer:

h = 147 - 16t^2.

Step-by-step explanation:

Use the following equation of motion

h = ut + 1/2 gt^2 where h = height, u = initial velocity , g = acceleration due to gravity and t = the time.

So here we have:

h = 14t + 1/2 * -32 * t^2

h = 14t - 16t^2

Does the residual plot show that the line of best fit is

Iteru [2.4K]

Answer:

$e_1 = 3.5-4.06= -0.56$

$e_2 = 2.3-2.09= 0.21$

$e_3 = 1.1-0.12= 0.98$

$e_4 = -2.2-(-1.85)= -0.35$

$e_5 = -4.1-(-3.82)= -0.28$

The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:

Yes, the points are in a curved pattern.

Step-by-step explanation:

The correct formula for the residuals is given by:

$e_i =y_i -\hat y_i$

Who represent the observed value minus the predicted. We can find the individual residuals and we got:

$e_1 = 3.5-4.06= -0.56$

$e_2 = 2.3-2.09= 0.21$

$e_3 = 1.1-0.12= 0.98$

$e_4 = -2.2-(-1.85)= -0.35$

$e_5 = -4.1-(-3.82)= -0.28$

The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:

Yes, the points are in a curved pattern.
