What is the kinetic energy of an arrow (of mass 230g) that is launched from a bowstring that is displaced 50 cm from rest and has a spring constant of 300 N/m? If it is fired straight up, at what height will it stop rising? Assume no friction.

A mass 3 kg is released from rest at a height of 5 meters and slides down a frictionless curve. There is a patch that is 3 meters long with a kinetic coefficient of 0.2. Beyond that friction patch is a spring with a spring constant of 400 N/m. (There is no friction under the spring.) Calculate the maximum compression distance (x) needed to stop the mass the first time It compresses the spring. Calculate where exactly the mass stops...

1) An archer fires an arrow from a bow. The arrow’s mass is 0.088 kg, and an average force of 110 N is exerted by the bowstring over a 0.78 m distance. Calculate the velocity of the arrow just after it is released by the bowstring by two methods: a) Calculate the arrow’s acceleration that is caused by the bowstring, and use kinematic equations to calculate the velocity at the end of the acceleration. Assume a constant acceleration that corresponds...

A- A spring, of mass 146 g, is extended a distance of 11.0 cm from its equilibrium position, pointed straight up in the air, and released so that it is launched straight upwards. If the spring has a spring constant k = 161 N/m, at what height above its initial position will the spring have an equal amount (magnitude) of kinetic and stored gravitational potential energy (relative to its initial height). After being launched, the spring is remains at its...

Consider a 3.0 kg mass on a spring on a horizontal surface. The
spring has spring constant 45 N/m. The static coefficient of
friction between the mass and the surface is µS = 0.30 and the
kinetic coefficient of friction is µK = 0.20
(a) When the mass is at x0 = 20 cm it is moving to the right
with speed 50 cm/s. Where does it first come to a stop? [Hint: use
energy considerations.]
(b) Once the mass...

A small 0.40-kg box is launched from rest by a horizontal spring
as shown in the figure below. The block slides on a track down a
hill and comes to rest at a distance d from the base of
the hill. The coefficient of kinetic friction between the box and
the track is 0.32 along the entire track. The spring has a spring
constant of 37.0 N/m and is compressed 30.0 cm with the box
attached. The block remains on...

1. (Work-Energy) Justin Bieber is to be launched as a human cannonball by being fired from a spring-loaded cannon. We would like for him to hit a target 550 ft downrange. The spring is to be compressed 6 ft in the cannon prior to "firing. Assume that Justin a 98 Ib particle, neglect friction in the barrel of the cannon and the drag during his projectile motion flight.
