In uniform circular motion, if speed remains constant, does the object accelerate? Why or why not?
Yes; because the direction of the speed is changing, therefore the velocity is changing

The surface is frictionless. In Case 1, a 2 kg block is set at rest on the inclined section. Upon release, the 2 kg block has an acceleration of 6 m/s2. In Case 3, what acceleration will the system of blocks have the instant that the 2 kg block is released?
4 m/s2

An amateur NASCAR driver is practicing driving at a constant speed on a perfectly circular track. If the course has a radius of 88m and the driver finished 20 laps in 10 minutes, what is the centripetal acceleration of the car?
T=(10*60)/20=30\sec
v=(2pir)/T=(2pi(88))/30=18.4
a_c=v^2/r=18.4^2/88=3.9m/s^2

A plane flies directly from city A to city B, which are separated by 2300 mi. From A to B, the plane flies into a 65 mi/h headwind. On the return trip from B to A, the wind velocity is unchanged. The trip from B to A takes less than the trip from A to B. What is the airspeed (assumed constant) of the plane relative to the air (that is, the airspeed) in m/s?
530 mi/hr = 237 m / s

NASA sends a satellite to a possibly habitable planet in a nearby galaxy. The satellite then orbits at 35,000m above the surface. Given the information below, calculate the gravitational acceleration at that of the new planet and the satellite's orbital speed.
M_p=3.5*10^30kg
R=1.2*10^10m
m_r=820kg
g=GM/R^2=(6.67*10^-11)(3.5*10^30)/(1.2*10^10)^2=1.6m\s^2
v_(sat)=\sqrt(GM/(R+d))=\sqrt ((6.67*10^-11)(3.5*10^30)/(1.2*10^10+35000)=139,478m/s
