The recoil of a shotgun can be significant. Suppose a 3.3.kg shotgun is held tightly by an arm and shoulder with a combined mass of 15.0 kg. Part A When the gun fires a projectile with a mass of 0.036 kg and a speed of 380 m/s, what is the recoil velocity of the shotgun and arm-shoulder combination? Express your answer to three significant figures and include appropriate units. НА ? Value Units Submit Request Answer

A point charge qı = 5.00 uC is held fixed in space. From a horizontal distance of 4.00 cm, a small sphere with mass 4.00 x 10-kg and charge 92 = +2.00 C is fired toward the fixed charge with an initial speed of 40.0 m/s. Gravity can be neglected. Part A What is the acceleration of the sphere at the instant when its speed is 26.0 m/s? Express your answer with the appropriate units. li MA ? m a...

A 212-kg projectile, fired with a speed of 133 m/s at a 63.0 angle, breaks into three pieces of equal mass at the highest point of its arc (where its velocity is horizontal). Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion; one of these moves vertically downward and the other horizontally Part A Determine the magnitude of the velocity of the third fragment immediately after the...

Phys201-1 Summer2020 <A HW (Part 1)Phys201 Problem 7.79 A block of mass m = 2.70 kg starts from the rest and slides down a 300 incline which is 3.60 m high. At the bottom, it strikes a block of mass M-7.50 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored Determine the speed of the block with mass m2.70...

The 0.3-kg pin P is constrained to move in the smooth curved slot, which is defined by the lemniscate (0.6 cos20) m. Its motion is controlled by the rotation of the slotted arm O A, which has a constant clockwise angular velocity of 0 = -3 rad/s. (Figure 1) r= Part A Determine the force arm O A exerts on the pin P when 0 = 0°. Motion is in the vertical plane. Express your answer to three significant figures...

Problem 18.87 Drops of an oil that has a mass density of 700 kg/m are released from a broken undersea oil pipe that is 1300 m below the ocean surface. Use 1000 kg/m for the mass density of ocean water Part A If the drops have an average diameter of 100 m, how long do they take to rise to the surface? Hint. The drops quickly reach terminal speed and experience a viscous drag force of magnitude F (0.0200 Pa...
