Q. A bullet leaves a standard 45-caliber pistol (5.0-in. barrel) at a speed of 262 m/s. If it takes 1 ms to traverse the barrel, determine the average acceleration experienced by the 16.2-g bullet within the gun and after that compute average force exerted on it.
Q. A ball rolling on a table has a velocity with rectangular components Vx=0.60m/s and Vy=0.80m/s. What is the displacement of the ball is an interval of 2.5 seconds?
A 240g ball and a 130g ball are connected by a 32 cm-long massless, rigid rod. The structure rotates about its center of mass at 150rpm.
Differentiate between the following three types of plain carbon steels.
A 160 m wide river flows due east at a uniform speed of 4.05 m/s. A boat with a speed of 7.2 m/s relative to the water leaves the south bank pointed in a direction 39o west of north. What is (a) magnitude and (b) direction of the boat's velocity r..
A man pushes a lawn mower on a level lawn with a force of 187 N. If 51 percent of the force is directed horizontally, how much work is completed by the man in pushing the mower 7.0 m.
A horizontal force of magnitude 100 N begins to pull directly on block. In unit-vector notation, what are the resulting accelerations of (a) block and (b) slab.
A 3.2 mass attached to a spring with a spring constant of 114 is oscillating in a vat of oil, which damps the oscillations. If the damping constant of the oil is 10kg/s, how long would it take the amplitude of the oscillations to decrease to 1.0% ..
Compute the mass of a ball and speed of a puck after collision.
Compute the amplitude and phase at the observation screen
A 60kg bicyclist rides his 7.8kg bicycle with a speed of 16m/s. How much work must be done by the brakes to bring the bike and rider to a stop.
How to discuss the results in relation to the objectives of the experiment of CENTRIPETAL FORCE? Next, how am i supposed to elaborate the results that I obtained if my results are confirmed the centripetal force theory.
Driving in your car with a constant speed of 13 m/s, you encounter a bump in the road that has a circular cross section, as indicated in the figure. If the radius of curvature of the bump is r = 29 m, find the apparent weight of a 59-kg person in you..
Block 1, of mass m_1 = 0.500 kg, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m_2. Suppose that the blocks accelerate with an acceleration of magnitude a = 0.550 m/s^2 and that coefficient of kinetic friction b..
