1. In 0.720 s, a 6.95-kg block is pulled through a distance of 3.70 m on a frictionless horizontal surface, starting from rest. The block has a constant acceleration and is pulled by means of a horizontal spring that is attached to the block. The spring constant of the spring is 460 N/m. By how much does the spring stretch in kg? 2. An object attached to a horizontal spring is oscillating back and forth along a frictionless surface. The...

When an archer pulls an arrow back in his bow, he is storing potential energy in the stretched bow. (a) Compute the potential energy stored in the bow, if the arrow of mass 5.05 10-2 kg leaves the bow with a speed of 32.0 m/s. Assume that mechanical energy is conserved. (b) What average force must the archer exert in stretching the bow if he pulls the string back a distance of 30.0 cm?

An archery bow is drawn a distance d 0.28 m and loaded with an arrow of mass m a spring with a spring constant of k 154 N/m, and the arrow flies with negligible air resistance. To simplify your work, let the 0.084 kg. The bow acts as gravitational potential energy be zero at the initial height of the arrow. 220 Part (a) How fast, in meters per second, will the arrow be traveling as it leaves the bow? aila...

47. An archer pulls the bowstring back for a distance of 0.470 m before releasing the arrow. The bow and string act like a spring whose spring constant is 425 N/m. (a) What is the elastic potential energy of the drawn bow? (b) The arrow has a mass of 0.0300 kg. How fast is it traveling when it leaves the bow?

A block of mass m=2.00 kg is attached to a spring of force constant k=500. N/m that lies on a horizontal frictionless surface. The block is pulled back 5.00cm and released. a) How much work was required to stretch the spring? b) What is the speed of the block when it is 2.50cm from the equilibrium point? c) What is the speed of the block at the equilibrium point?

A high-quality potato cannon can fire a potato with a muzzle speed of 30.0 m/s. If I am standing on the ground and fire this potato cannon at an angle of 50.0° above the horizontal, what is the potato's speed when it reaches a height equal to one-half of its eventual maximum height?

In the Hunger Games, Katniss shoots an arrow at an apple in a pig’s mouth using a longbow. After careful analysis of the scene, my daughter and I estimate she is standing 12 m away and 3.5 m below her target. A typical shot from a longbow reaches speeds of 55 m/s. a) At what angle above the horizontal must she fire the arrow? There are two solutions (what do they correspond to?) and which one would be the one...
