Answer:
The range of the projectile is 66.7 meters.
Explanation:
The range of a projectile is given by the following expression as :
..............(1)
The range can be calculated using equation (1). Putting the values of all parameters we get :
R = 66.7 meters
So, the range of the projectile is 66.7 meters. Hence, this is the required solution.
Answer:
rpm
Explanation:
Given that rotational kinetic energy =
Mass of the fly wheel (m) = 19.7 kg
Radius of the fly wheel (r) = 0.351 m
Moment of inertia (I) =
Rotational K.E is illustrated as
Since 1 rpm =
Answer:
The question is incomplete however this kind of questions about determinate the angular speed and taking a reference of days rotating the first star.
w=0.11312 rad/s
Explanation:
The situation is about a two star the question is incomplete, miss the time rotate one star so we assume the first star rotated once in 30 days so:
Angular momentum
The inertia
The momentum must be conserved so
notice don't have to know the mass or use the density however at the end can determinate
Time can determinate the frequency so determinate angular speed of the first star
