Problem 37 (Plug-n-chug). The 25-lb block has an initial speed of vo = 10 ft/s when it is midway between springs A and B. After striking spring B, it rebounds and slides across the horizontal plane toward spring A. The coefficient of kinetic friction between the plane and the block is Hk = 0.4. If the block makes it to spring A, then choose that option below; otherwise, if the block comes to rest before reaching spring A, then determine the total distance traveled by the block.

(d) reaches spring A

(c) 3.1 ft

(b) 2.7 ft

(а) 1.9 ft

(e)None of these

Question 45467

Dynamics

As a part of a robotics competition, a robotic arm with a rigid open hand at C is to be designed so that the hand catches an egg without breaking it. The egg is released from rest at t = 0 from point A. The arm, initially at rest in the position shown, starts moving when the egg is released. The hand must catch the egg without any impact with the egg. This can be done by specifying that the hand and the egg must be at the same position at the same time with identical velocities. A student proposes to do this using a constant value of 0 for which (after a fair bit of work) it is found that the arm catches the egg at /= 0.4391 s forÖ = -13.27 rad/s2. Using these values of t and Ö, determine the acceleration of both the hand and the egg at the time of catch.Then, explain whether or not using a constant value of 0, as has been proposed, is an acceptable strategy.
