Homework Equations
Centripetal Acceleration: a=v2/r or a=w2r
where a= Centripetal Acceleration
v= Linear Velocity
r= Radius
w=angular velocity
The Attempt at a Solution
Question Number 1: Drew a diagram of a circular with one point being O, another being P and another being A, Radius of Circle is 3.6m, and joined O and P to a 25o
MIGHT BE WRONG
Question Number 2:
Turn of 90o takes 0.4 seconds
Therefore 90degree/0.4 seconds = 225 degrees per second or
Therefore using equation
a=w2r
a=2252*0.45
a=22781.25degrees/sec
Pretty sure this is also wrong as for acceleration, it seems too fast
Question Number 3:
Drew diagram--> Circle[Radius 12 cm][2 Revolutions per second]
a=w2r
Question Number 4:
Honestly have no idea how to start
