A pendulum is taken to another planet where it swings back and forth exactly 14 times every 24.34 seconds. The pendulum's arm is 0.24 LaTeX: mm long. What is the acceleration due to gravity on this planet in units of m/s?

Aparticle initially located at the origin has an acceleration of = 2.00ĵ m/s2 and an initial velocity of i = 8.00î m/s. find (a) the vector position of the particle at any time t (where t is measured in seconds), (b) the velocity of the particle at any time t, (c) the position of the particle at t = 7.00 s, and (d) the speed of the particle at t = 7.00
