How many complete revolutions are needed to draw the angle 725°?
2 answers:
Answer:
Explanation:
We know that 1 complete revolution is equal to 360 degrees. We need to find the number of complete revolution needed to draw the angle of 725 degrees.
Since, 1 revolution = 360 degrees
or
or
So, to draw an angle of 725 degrees, there are 2 revolutions. Hence, this is the required solution.

The distance covered by the object is 42.4 m
Explanation:
The motion of the object is a uniformly accelerated motion (at constant acceleration), therefore we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the object in this problem, we have:
u = 0 (it starts from rest)
v = 24 m/s (final velocity)
Solving for s, we find the distance travelled by the object:
