Homework Statement
A cat leaps over a 1.5m wall with a speed of 15m/s and at an angle of 35 degrees. The cat lands on the edge of a ledge that is 1.5m tall, how far is the ledge from the wall?

Projectile Analysis:
Distance = 40m
Angle = 45 degrees
Velocity = 19.8m/s
Can I use the projectile velocity to calculate centripetal acceleration?
Other Given:
Radius/length of arm: 40cm
Pull back angle: 60 degrees
Spring length: 15cm
Mass of ball is 46g
Time(ball): 2s
What else can I...
Not really for the projectile since it's a standard golf ball but whatever optimizes the speed of the arm is a bonus. However the tighter my springs are the more often they pop off the circle screws and the tightness also dent my pivot arm (thin metal pole).
Would rotating the throwing arm (2cm by 4cm) to its side reduce air resistance due to the smaller surface area? (Imagine a palm vs karate chop scenario).
