Please help me with this physics question!! I am so confused and frustrated with physics!!
A cyclist is riding over the top of a hill traveling at a speed of 6.71m/s when their chain and brake cable break so they are no longer able to apply any force to change their speed. The hill they begin at the crest is 25.6m above the bottom of the valley. Ignore friction and air resistance.
a) After they coast to the bottom of the first hill, what is their speed?
b) Next, they come to a second hill. This hill is a straight ramp with an angle of 25 degrees with respect to the horizontal. What distance will the cyclist travel along the ramp before they come to a stop and can safely dismount?
c) Let's say a third small hill 12m above the valley floor is added to the middle of the first two. Would this change the outcome? Why or why not?

Hey I got this question wrong
on my physics test so if you could help me find the right answer
and describe how you got it that'd be great. Thanks!
8. A cyclist is traveling at a constant velocity of 5.00 m/s. The cyclist approaches a stationary musician playing a note of frequency 281 Hz. The air is still and the speed of sound is 340 m/s. What is the frequency of the note that the cyclist hears? (1 point)...

Constants A 9.00 m uniform beam is hinged to a vertical wall and held horizontally by a 5.00 m cable attached to the wall 4.00 m above the hinge, as shown in the figure below (Figure 1). The metal of this cable has a test strength of 1.10 kN , which means that it will break if the tension in it exceeds that amount. Part A What is...

Help please I am so confused
1. Assume that nominal wages are sticky and that firms determine the level of employment in the short run. Use an AD/AS diagram to model the goods market, a labor demand/supply diagram to model the labor market, and the loanable funds diagram to model the financial market. Assume that in addition to the real interest, consumption depends on current disposable income and the present value of future disposable income. Speculate what would happen in...
