In flight, a rocket is subjected to four forces; weight, thrust, lift, and drag. Forces are vector quantities that have both a m
agnitude
and a direction. Imagine that the rocket is about to lift off the launch pad. According to Newton's third law of motion, what force is
critical to the success of its upward motion?
A)
drag
B)
Lift
c)
thrust
D)

Answer:
a = 0.1 s b. 10 s
Explanation:
Given that,
The frequency in circular motion, f = 10 Hz
(a) Let T is the period of itsrotation. We know that,
T = 1/f
So,
T = 1/10
= 0.1 s
(b) Frequency is number of rotations per unit time. So,
Hence, this is the required solution.
