5) A person on a motor cycle gains a speed of 10kmph to 60kmph in 10 secs. The angular rotation of the needle in the speedometer is about 200 degrees. What will be the angular speed in degrees/sec?

The angular speed of the speedomenter needle while accelerating at that rate is:
w = (200/360)*(2 pi)rad/10 sec
= (5/9)*2*pi/10 = pi/9 radians/s
w = (200/360)*(2 pi)rad/10 sec
= (5/9)*2*pi/10 = pi/9 radians/s
