Question: Starting from rest, the toy plane flies around a circle of radius 2m, three times in 3 seconds. There is constant tangential acceleration, fins the magnitude of the acceleration at the end of 0.5s.
My solution (most likely wrong):
Circumference= 2pir= 4pi= 12.56631
Distance traveled in 3 rounds (or in 3 seconds )
= 3* circumference= 37.699m.
At 0.5 seconds (1/6th of the total time), distance travelled
= 37.699/6= 6.2831m.
Velocity at 0.5s
= displacement/time = 6.2831m/0.5s= 12.56631 m/s.
( I knew I didn’t have to do all those steps but I did to help myself)
Acceleration at 0.5s
a= v^2/r = (12.56631)^2/2 = 78.96 m/s^2.
Am I okay? Or did I make a mistake, if so, where did I go wrong?
Thanks in advance for the help!
