Constant A spring loaded gun (with a spring constant, k) is compressed. It launches a ball of mass, m, directly upwards. At height, h, the ball is recorded as having a velocity of v. V h Part A The spring in the gun was compressed by a length, x, given by: 2mgh x = k x = m(v²+2gh) x = k 2m(v²+gh) x =

Q24. As shown in the image below, the 16-kg block A and the 42-kg block B connected by the weightless, frictionless pulley system are released from rest. Determine the speed of block B when block A has displaced downwards by 0.7 m. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. A Answer: d O [o k B

Ⓒ Macmillan Learning A block of mass m = 6.23 kg is attached to a spring that is resting on a horizontal, frictionless table. The block is pushed into the spring, compressing it by 5.00 m, and is then released from rest. The spring begins to push the block back toward the equilibrium position at x = 0 m. The graph shows the component of the force (in newtons) exerted by the spring on the block versus the position of the block (in meters) relative to equilibrium. Use the graph to answer the questions. How much work W is done by the spring in pushing the block from its initial position at x = -5.00 m to x = 2.20 m? W = V = -59.04 Incorrect What is the speed of the block when t reaches x 2.20 m? 2.41 Incorrect Umax = What is the maximum speed max of the block? 3.63 J Incorrect m/s m/s 6 5. 4. 3. 2 ↓ L₁ -3. -4. -5. -6.
