In the design of a timing mechanism, the motion of pin p in the fixed circular slot is controlled by the guide a, which is being elevated by its lead screw. guide a starts from rest with pin p at the lowest point in the circular slot, and accelerates upward at a constant rate until it reaches a speed of 60 mm/s at the halfway point of its vertical displacement. the guide then decelerates at a constant rate and comes to a stop with pin p at the uppermost point in the circular slot. determine the n- and t-components of acceleration of pin p once the pin has traveled 30° around the slot from the starting position.

She sold 135 peaches, because if you multiply 2.50 eith 135, you'd get 337.5, the 0 can be added or not.

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
