Answer:
∆PE = 749.7 J
At 0.9 m high, PE = 793.8 J
At 1.75 m high, PE = 1543.5 J
Answer:
6.41m/s2
Explanation:
unit conversion:
78 rev/min = 78rev/min * 2π rad/rev * 1/60 min/sec = 8.168 rad/s
12 in = 12 in * 2.54cm/in = 30.48 cm = 0.3048 m
So the record accelerate from rest to 8.168 rad/s, its (assuming constant) angular acceleration would be

From here we can calculate the angular velocity of the bug at t2 = 1.5s

Its centripetal acceleration would then be

If a person returns to the position he started again. like moving in a circle track
