A 4.8-kg block attached to an ideal spring executes simple harmonic motion on a frictionless horizontal surface. At time t = 0.00 s, the block has a displacement of a velocity of and an acceleration of The force constant (spring constant) of the spring is closest to

A 6.52 gram bullet is fired into a 0.601 kg block attached to the end of a 0.670 m non uniform rod of mass 0.698 kg. The block-rod-bullet system then rotates in the plane of the figure, about a fixed axis at A. The rotational inertia of the rod alone about A is 0.0550 kg m2. If the angular speed of the system about A just after impact is 1.96 rad/s, what is the bullet’s speed (in m/s) just before the impact? Treat the block as a particle.

Astronaut Jennifer’s lifeline to her spaceship comes loose and she finds herself stranded, “floating” 100 m from the mothership. She suddenly throws her 2.00-kg wrench at 20 m/s in a direction away from the ship. If she and her spacesuit have a combined mass of 200 kg, how long does it take her to coast back to her spaceship?

Three forces, 1, 2, and 3, all act on an object, as shown in the figure. The magnitudes of the forces are: F1 = 80.0 N, F2 = 60.0 N, and F3 = 40.0 N. The resultant force acting on the object is given by

Estimate the number of times an average person’s heart beats in a lifetime. Assume the average heart rate is and a life span of 75 years.

Continuing with the DooDads Integrated Supply Chain whose incentives are the most closely aligned? Choose the best answer. This Problem Counts 2 Points

Consider both Statements. Statement 1 Management seeks to select suppliers primarily for speed, flexibility, and quality when using an efficient supply chain model. Statement 2. The goal of the Newsvendor model is to maximize expected revenue.

A boy kicks a football with an initial velocity of 20 m/s at an angle of 25° above the horizontal. If we neglect air resistance, the magnitude of the acceleration of the ball while it is in flight is

(True/False). Trial and error can be used to determine the weights for a weighted moving average forecast.
