Motion on a Frictionless Incline
Measuring the acceleration:
Mass of Cart=501.69 g + 0.01 = 0.50169 kg + 0.00001
Inclination 1=8.00
Inclination 2=8.92
Inclination 3=10.9
h= 25.10 cm = 0.2510 m
h= 27.91 cm = 0.2791 m
h= 34.08 cm = 0.3408 m
z = 180.40 cm =

Projectile motion
1. For what launching angle would you expect a maximum range? Explain.
We expect the max range for = 45 because range s= (vo2/g) sin2. Consequently, for
constant vo (and g is already a constant), the range is max when sin2 is max and equ
