Angular velocity is the rate of change of angle of a body, i.e. omega = v / r = (2*pi*r)/ r*t = (2*pi)/ T. where T is the time period of whatever is rotating and r is the radius of the circle. So if a circular disc is spinning at 1 m/s then the angular velocity of it is 2*pi radians/ second.
<span>F = m*a = 7000kg * 9.8N/kg = 68,600 N.
68,600 N is your answer

Answer: unit n/c
Explanation: This should be the answer because I just asked my Physics Teachers I hope this is correct
Hope This Helps :)
Answer:
34 m/s
Explanation:
The law of conservation of linear momentum dictates that the sum of initial and final momentum should be equal. Momentum is a product of mass and velocity.
Since the canon recoils, its recoil velocity is opposite hence
MV=nu where M and n are mass of cannon and cannoball respectively, v and u are the velocities of cannon and cannon balls respectively.
Substituting 200 kg for M and 1.7 m/s for v then 10 kg for n
200*1.7=10u
U=200*1.7/10=34 m/s
Answer:
The relativistic speed of a particle is 
Explanation:
Given that,
Time = 6 sec
Force = 1
Mass of the particle 
We need to calculate the acceleration
Using formula of acceleration
Put the value into the formula
We need to calculate the velocity after 6 sec
Using equation of motion
Put the value
The velocity in term of c
Hence, The relativistic speed of a particle is
