In the sport of hammer throwing, athletes rotate a ball connected to a string around their body before throwing it away. The hammer has a mass of 8.1 kg and the rope that the athlete holds has a length of 135 cm. If the maximum force that the thrower can exert on the rope is 2950 N, a) What will be the velocity of the hammer at release?
b) What is the period of the thrower's rotation if it is assumed that the thrower rotates the hammer in a perfectly horizontal circle?

Sorry i don’t know what to do

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
