A single conservative force acting on a particle varies as vector F = (-Ax + Bx6)i hat N, where A and B are constants and x is in meters. Accurately round coefficients to three significant figures...

When a 3.80 kg object is hung vertically on a certain light spring that obeys Hooke's law, the spring stretches 2.80 cm. (a) If the 3.80 kg object is removed, how far will the spring...

I need to know the distance the ball will travel for a special work for physics class and just to learn in general.

A toy cannon uses a spring to project a 5.29 g soft rubber ball. The spring is originally compressed by 5.03 cm and has a force constant of 8.05 N/m. When the cannon is fired, the ball moves 14.6...

A bead slides without friction around a loop-the-loop as shown in the figure below. The bead is released from a height h = 3.00R. http://www.webassign.net/pse/p8-15...

A 1.00-kg block is pushed along a rough horizontal floor with a horizontal force of 5.00 N for a distance of 5.00 m. If the block is moving at a constant velocity of 4.00 m/s, find... The...

An object with mass m1 = 5.00 kg, rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m2 = 9.0 kg, as...

Two packing crates of masses m1 = 10.0 kg and m2 = 6.50 kg are connected by a light string that passes over a frictionless pulley as in Figure P4.26. The 6.50 kg crate lies on a smooth incline of...

During a circus act, an elderly performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of 27.0 kg and its horizontal component of velocity is 6.00 m/s when the...

What is the speed (in m/s) of a garbage truck that is 1.25 ✕ 104 kg and is initially moving at 25.1 m/s just after it hits and adheres to a trash can that is 77.5 kg and is initially at rest? (Enter...

Two football players collide head-on in midair while trying to catch a thrown football. The first player is 96.5 kg and has an initial velocity of 6.25 m/s, while the second player is 120 kg and has...

A potential energy function for a two-dimensional force is of the form U = 3 x5y - 3 x. Find the force that acts at the point (x, y). (Use x and y as appropriate.) __________i+...

A single conservative force acting on a particle varies as vector F = (-Ax + Bx6)i hat N, where A and B are constants and x is in meters. Accurately round coefficients to three significant figures...

A 110 g bullet is fired from a rifle having a barrel 0.580 m long. Assuming the origin is placed where the bullet begins to move, the force (in newtons) exerted by the expanding gas on the bullet...

9. A 0.05 kg bullet moving vertically upwards at 125 m/s hits a stationary 2.6 kg block hanging from a 5.00 m long string. The block then soars upward until it reaches a maximum height (you may assume...
