Answer:
56.6 m/s
Explanation:
The velocity of an object accelerating at constant acceleration is given by the following SUVAT equation
where
u is the initial velocity
a is the acceleration
t is the time
For the object in the problem,
u = 0 since it starts from rest
is the acceleration
Substituting t = 12.3 s, we find the velocity at that time:
C. It acts perpendicular to the velocity and it's directed towards the center
hope this helps :)
Can you elaborate more on the question please

Explanation:
Answer:
No work is done since no distance is given
Explanation:
Since no distance is given, the force is not doing any work
No work is done by the man since we do not know the distance or displacement.
Work is only said to be done when the force applied on an object moves it through a particular distance.
Work done = Force x distance.
Since no distance is given in this problem, we can as well assume that the force applied is doing no work on the object.
