A 1.0-kg block and a 2.0-kg block are pressed together on a horizontal frictionless surfacewith a compressed very light spring between them. They are not attached to the spring. Afterthey are released and have both moved free of the spring the lighter block will have more kinetic energy than the heavier block. the heavier block will have more kinetic energy than the lighter block. both blocks will both have the same amount of kinetic energy. both blocks will have equal speeds. the magnitude of the momentum of the heavier block will be greater than the magnitude of the momentum of the lighter block.

4) An archer draws his compound bow and shoots an arrow. The 25 g arrow leaves the bow with a velocity of 95 m/s. The power stroke of the bow is 57 cm; that is, the bowstring exerts force on the arrow through a displacement of 57 cm. The peak draw weight of the bow is 312 N. (This is the maximum force that the archer has to exert on the bowstring.) a. How much kinetic energy does the arrow have after release? b. If shot straight up, how high will the arrow go?
Ballistic pendulum: The height h can be found using conservation of mechanical energy after the object is embedded in the block. If a ballistic pendulum of mass 1.17 kg rose to a height of 0.12 m after being hit by a 11 g bullet, find the initial speed of the bullet at which it was shot. Ignore air resistance.

Below is a conservation of energy problem. The solution to this problem is provided. Assess whether the solution provided is correct or incorrect AND EXPLAIN WHY. = 4.6 kg block is at rest against a horizontal spring that is compressed by 0.40 m. The spring has a spring constant of k₁ 2750 N/m. After leaving the spring, it travels up a 28° incline to a height of 2.8 m. At the top of the hill is a second spring with a spring constant of k₂ = 350 N/m. The horizontal portions are frictionless, but the hill has a coefficient of kinetic friction equal to uk = 0.16. The final velocity of the block is 9.78 m/s. How much is the second spring compressed by when the block comes to a stop against it?

The magnitude of the force required to compress an imperfect horizontal spring a distance x is given by Fbs = kx +bx^3 where k=120N/m and b=18N/m^3. If you use a 7.5kg block to compress the spring a distance of 1.6m and then let it go, what speed will the block have when it leaves the spring? Assume the surfaces are smooth enough that any frictional forces can be neglected.
The elastic energy stored in your tendons can contribute up to 35% of your energy needs when running. Sports scientists find that (on average) the knee extensor tendons in sprinters stretch 42 mm while those of nonathletes stretch only 35 mm. The spring constant of the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes? Express your answer to two significant figures and include the appropriate units. ► View Available Hint(s) AU = μA Value N m

A teflon block (m = 80 g) is initially at rest when it is launchedhorizontally across a level tabletop with negligible friction.The block is launched using a spring with k = 790 N/m thathas been compressed by ∆x = 5.0 cm. When the block reachesthe edge of the flat table (height h = 1.5 m) it falls down tothe floor below. Let Vf be the speed of the block just before it hits the floor. As m approaches infinity, what does Vf approach? Why?
