A0.50mkg mass at the end of a spring oscillates in simple harmonic motion with an amplitude of 0.15m. if the mass has a maximum speed of 1.25 m/s as it passes the equilibrium position of the spring, then determine the following quantities. a. the spring constant, b. the maximum acceleration, c. the frequency, f, of the oscillation, d. the total energy of the mass spring system.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
