A 69.0-kg athlete leaps straight up into the air from a trampoline with an initial speed of 8.9 m/s. The goal of this problem is to find the maximum height she attains and her speed at half maximum height. Write the general equation for energy conservation and solve for the velocity at half the maximum height. Substitute and obtain a numerical answer.
The figure sows a block and track system. All locations indicated by solid black lines are frictionless. Tan has line is a patch of friction with coefficient ?k = 0.360 whose length is d = 1.45 meters. The small block m has a mass of 0.58 kg and is initially sliding with a speed of v1 = 3.59 m/sec on the raised surface with a height og y1 = 0.532 m. The spring has a spring constant of k = 25.1 N/m.
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.

= 2. Refer to the diagram below. A spring-loaded launcher is aimed vertically upward, and compressed 0.13 m beyond its equilibrium position, then locked into place. The spring constant is k 60000 N/m. A block of mass 2 kg is placed on the launcher. When the spring lock is released, the block is launched upward to a maximum height, H. What is this height, H, if the block loses 17 Joules of mechanical energy to air resistance (during its upward flight)? Show all calculations. пиши before launch H = ? риши after launch
