The momentum of a neutron p = 586.25 kg m / s.
<u>Explanation:</u>
The product of mass and the velocity gives the momentum of an object and it is a vector quantity. It is denoted by the letter p. The unit of momentum is kilogram meter per second (or) kg m / s.
Given mass m = 1.675 10, velocity v = 3.500
10
Momentum, p = mv
where m represents the mass,
v represents the velocity.
momentum p = (1.675 10)
(3.500
10)
momentum p = 586.25 kg m / s.
Answer:
The torque needed is 46.08 Nm
Explanation:
Given;
angular velocity, ω = 12 rad/s
time of motion, t = 0.5 s
length of the baton, r = 0.8 m
mass of the baton, 0.5 kg
The torque needed to reach the angular velocity is given by;
τ = F x r
where;
F is the centripetal force of the baton
r is the length of the baton = radius of the circular motion of the baton
Torque is given by;
Therefore, the torque needed is 46.08 Nm
