Q: If a fish is attached to a vertical spring and slowly lowered

If a fish is attached to a vertical spring and slowly lowered to its equilibrium position, it is found to stretch the spring by an amount d. If the same fish is attached to the end of the unstretched...

Q: You are an industrial engineer with a shipping company. As part

You are an industrial engineer with a shipping company. As part of the package-handling system, a small box with mass 1.60 kg is placed against a light spring that is compressed 0.280 m. The spring ha...

Q: A basket of negligible weight hangs from a vertical spring scale of

A basket of negligible weight hangs from a vertical spring scale of force constant 1500 N/m. (a) If you suddenly put a 3.0-kg adobe brick in the basket, find the maximum distance that the spring will...

Q: A 3.00-kg fish is attached to the lower

A 3.00-kg fish is attached to the lower end of a vertical spring that has negligible mass and force constant 900 N/m. The spring initially is neither stretched nor compressed. The fish is released fro...

Q: You are designing an amusement park ride. A cart with two

You are designing an amusement park ride. A cart with two riders moves horizontally with speed v = 6.00 m/s. You assume that the total mass of cart plus riders is 300 kg. The cart hits a light spring...

Q: A 0.500-kg block, attached to a spring

A 0.500-kg block, attached to a spring with length 0.60 m and force constant 40.0 N>m, is at rest with the back of the block at point A on a frictionless, horizontal air table (Fig. P7.69). The mas...

Q: A small block with mass 0.0400 kg slides in a

A small block with mass 0.0400 kg slides in a vertical circle of radius R = 0.500 m on the inside of a circular track. During one of the revolutions of the block, when the block is at the bottom of it...

Q: A small block with mass 0.0500 kg slides in a

A small block with mass 0.0500 kg slides in a vertical circle of radius R = 0.800 m on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block’...

Q: You are asked to design a spring that will give a 1160

You are asked to design a spring that will give a 1160-kg satellite a speed of 2.50 m/s relative to an orbiting space shuttle. Your spring is to give the satellite a maximum acceleration of 5.00g. The...

Q: A small rock with mass 0.12 kg is fastened to

A small rock with mass 0.12 kg is fastened to a massless string with length 0.80 m to form a pendulum. The pendulum is swinging so as to make a maximum angle of 45° with the vertical. Air resistance i...
