Question:
A fighter pilot is being trained in a centrifuge of radius 15m. it rotates according to theta=0.25(t^3) + ln(t+1) befor it stabilises (theta in radians). what are the magnitudes of the pilots:
a) angular velocity: d(theta)/dt at t = 4 (12.2 rad/sec)
b) linear velocity: 12.2 * 15
c radial acceleration: 2nd derivative of theta=0.25(t^3) + ln(t+1) at t = 4 (5.96rad/sec^2)
d) tangential acceleration: 5.96 * 15
Are b and d just the angular values times the radius that's if a and c are right in the first place??
Thanks
