Out of the 5 questions pick the easiest 3 and answer them. Just the answer is fine no need to show steps.

A 0.400 kg mass is attached to a vertical spring with a force constant of 295 N/m. The mass is pulled down 10.50 cm and is released. By how much is the spring stretched when its speed is 0.500 m/s? Give your answer in cm to 1 decimal place. 2. A 0.875 kg mass is attached to a vertical spring with a force constant of 75.0 N/m. The mass is pulled down by 5.00 cm before being released. What is the first time after it is released that it reaches maximum speed? Give your answer in seconds to 3 decimal places. Do NOT include units in your answer. 3. The velocity of a mass on a vertical spring is given by v(t)=-3.00sin(1.50t) where velocity is measured in cm/s. What is the acceleration of the mass at t=0.60s? Give your answer in cm/s' to 2 decimal places. If the acceleration is negative include a negative sign in your answer. If the acceleration is positive do NOT include the sign in your answer. Regardless of the sign do NOT Include units in your answer What is the smallest positive value of w that will make the expression 5.0 GOS(2WIT) = -5.07 Ow = 3x Ow - " OW = 1 Ow = 5. Considering a mass attached to a horizontal spring undergoing simple harmonic motion after being pulled a horizontal distance x from equilibrium Which of the following statements is NOT correct m X m The larger the mass the smaller the speed is at equilibrium The speed of the mass at equilibrium depends on the period of the simple harmonic motion The speed of the mass at equilibrium depends on the size of the spring constant The speed of the mass at equilibrium depends on the magnitude of x
