Apendulum is made of a small sphere of mass 0.250 kg attached to a lightweight string 1.20 m in length. as the pendulum swings back and forth, the maximum angle that the string makes with the vertical is 34.0∘. friction can be ignored. at the low point of the sphere's trajectory, what is the kinetic energy of the sphere

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
