Answer:
a
The number of radians turned by the wheel in 2s is
b
The angular acceleration is
Explanation:
The angular velocity is given as
Now generally the integral of angular velocity gives angular displacement
So integrating the equation of angular velocity through the limit 0 to 2 will gives us the angular displacement for 2 sec
This is mathematically evaluated as
Now generally the derivative of angular velocity gives angular acceleration
So the value of the derivative of angular velocity equation at t= 2 gives us the angular acceleration
This is mathematically evaluated as
so at t=2
Two of Newton's laws, properly combined with geometry and calculus, then mixed, stirred and massaged, produce orbital motion.
==> Law of universal gravitation (gravity)
==> Second law of motion ( F=ma ).
Answer: 2 sec means 1 sec each way
1522 m/s x 1 s = 1522 m
Explanation:
-- The spaceship's AVERAGE speed during the acceleration is
(1/2) (58 m/s + 153 m/s))
= (1/2) (211 m/s)
= 105.5 m/s .
In 12 seconds at an average speed of 105.5 m/s,
the ship covers
(105.5 m/s) (12 sec) = 1,266 meters .
