Question

**1S-1.**

**Problem Description:**

A hammer head \( H \) having a weight of 0.3 lb is moving downwards at 40 ft/s when it strikes the head of a nail of negligible mass and drives it into a block of wood. Find the impulse on the nail if it is assumed that the grip at \( A \) is loose, the handle has a negligible mass, and the hammer stays in contact with the nail while it comes to rest.

**Diagram Explanation:**

The image depicts a hammer being held at point \( A \) on the handle, striking a nail vertically downward. The hammer head \( H \) is shown moving at a velocity of 40 ft/s towards the nail embedded in a block of wood.

The double pulley shown in the figure is formed by two wheels that are coupled to each other. The complete pulley (formed by the two wheels) has a mass of 15 kg and a turning radius of 110mm. Block A has a mass of 40 kg. If a force of 2 kN is applied to the tied rope of the inner pulley wheel, determine the speed of block A after 3 seconds. At the beginning, the whole system was at rest. Disregard the mass of the string and consider that the moment of inertia (kg.m²) of the complete pulley is given by IP = mko²where m is the mass of the pulley and Ko is the radiusspinning

The collar with mass of 0.7 kg is released from rest at position A and travels down the smooth circular rod in the vertical plane. If the velocity of the collar at Point C is 3.3 m, determine the tangential component of acceleration of the collar (in m) at Point C. The spring has a stiffness of k = 140 N and an unstretched length of 0.5 meters. Consider R = 1.7 meters, 0 = 33°, and g =10 A m R/2 D В R
The uniform slender rod (7.1 kg) is pinned at point O. If a 5.4-g bullet shoots into the rod with a speed of 660 m/s and becomes embedded in it, determine the total angular momentum H (in kg.m²/s) about point O immediately after that. The rod and the bullet are considered one system. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point.
