Sry, but this still leaves me with the same problem I already figured out question a. I know the formula for question b, but my problem is I don't know what to put for displacement. How would i figure out d1 and d2 in the formula. For question c I am not sure how to solve this question so how...
Question: A rolling ball has an initial velocity of -1.5 m/s.
a. If the ball has a constant acceleration of -0.23 m/s^2, what is its velocity after 2.2s?
b. What was its average velocity during that time interval?
c. How far did it travel in this time interval?
So far i got:
a. V=...
Calculate the period of the Earth's moon if the radius of orbit was twice the actual value of 3.9 x 10^8 m.
a. 1.13 x 10^6 s or 13 days
b. 2.3 x 10^6 s or 26 days
c. 5.14 x 10^6 s or 59 days
d. 6.85 x10^6 s or 79 days
So far I got: v=velocity; T=time; h= hieght from surface
v=?
T=...
State the period and phase shift of the function y= -4 tan (1/2x + 3pie/8).
I know the answer is pie; -3pie/8, but I don't understand the process could someone explain how the period and phase shift are found in these functions.
The mean distance between the Earth and the moon is 3.84x10^8 m, and the moon has an orbital period of 27.3 days. Find the distance from Earth of an artificial satellite that has an orbital period of 8.5 days.
a. 1.76x10^8 m
b. 1.76x10^4 m
c. 1.76x10^10 m
d. 5.24x10^8 m
So far I got:
I...
A 50 kg trunk rest on a ramp at 18 degrees. What is the parallel-component of the weight?
a. 15.5 N
b. 47.6 N
c. 151 N
d. 466 N
So far I got:
I used the formula Fgx = W sin 0.
Fgx= -(490 N) sin(18)
My answer was 368, as you see it is not one of the choices. Am i leaving out a step...
A high jumper falling at 3.9 m/s, lands on a foam pit and comes to rest, compressing the pit a distance of 0.43 m. If the pit is able to exert an average force of -1100 N on the high jumper in breaking the fall, what is the jumper's mass?
I don't know where to begin so anything can...
