Answer:
f = 3.97 Hz
Explanation:
Given that,
Centripetal acceleration,
The radius of motion is 0.02 m
The formula for the centripetal acceleration is given by :
The speed of an object in a circular path is given by :
t is time period
Also, f=1/t (f is frequency)
Hence, the frequency of motion s 3.97 Hz.
The 2 requirements for glue to work are adhesion and cohesion
Answer:
427.196 m
Explanation:
u = Initial velocity = 312 m/s
t = Time = 1.4 s
s = Displacement
a = -9.8 m/s² (because the bullet is decelerating as the bullet is going straight up)
Equation of motion
So, Displacement at 1.4 seconds is 427.196 m
