Juggles the clown stands on one end of a teeter-totter at rest on the ground. bangles the clown jumps off a platform 2.2 m above the ground and lands on the other end of the teeter-totter, launching juggles into the air. juggles rises to a height of 3.8 m above the ground, at which point he has the same amount of gravitational potential energy as bangles had before he jumped, assuming both potential energies are measured using the ground as the reference level. bangles' mass is 70 kg. what is juggles' mass?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
