Acar is traveling around a horizontal circular track with radius r = 210 m at a constant speed v = 16 m/s as shown. the angle θa = 35° above the x axis, and the angle θb = 53° below the x axis.
1. what is the magnitude of the car’s acceleration?
2. what is the x component of the car’s acceleration when it is at point a
3. what is the y component of the car’s acceleration when it is at point a
4. what is the x component of the car’s acceleration when it is at point b
5.what is the y component of the car’s acceleration when it is at point b
6.as the car passes point b, the y component of its acceleration is

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
