    SECTION 3 FORMATIVE ASSESSMENT O Reviewing Main Ideas 1. If the spring of a jack-in-the-box is compressed a distance of 8.00 cm from its relaxed length and then released, what is the speed of the toy head when the spring returns to its natural length? Assume the mass of the toy head is 50.0 g, the spring constant is 80.0 N/m, and the toy head moves only in the vertical direction. Also disregard the mass of the spring. (Hint: Remember...

    A wooden block with mass 1.95 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 35.0degree (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 4.00 m up the incline from A, the block is moving up the incline at a speed of 6.15 m/s and is no longer in contact with the spring. The coefficient of kinetic between the...

    A spring with spring constant k is positioned vertically and then compressed from its equilibrium length by a distance Delta y (Figure 1). A ball of mass m is placed on top of the spring, and is launched into the air when the spring is released (this setup is similar to the projectile launcher seen earlier in the semester). The ball travels to a maximum height h_max. Using the Work-Kinetic Energy theorem, determine h_max in terms of the given variables...
