Question

PH 221 In Class Work 1. A particle falls with the acceleration due to gravity which has magnitude 9.8 m's At time , 0 the particle is released from rest (i.c., initial velocity ve0) at a height of 100 m from the ground. a.Make a sketch representing the initial conditions of the problem showing: i. The origin and direction of the y-axis. ii. The position of the particle at , 0. iii. The velocity of the particle at to-0. iv. The acceleration of the particle. bFind the position y of the particle at time 3s. Explain the meaning of the sign of the position y) c. Find the displacement Ay of the particle between :0 and 3s (Explain the meaning of the sign of the displacement Δ d Find the instantancous velocity vof the particle at time3s. (Explain the meaning of the sign of the velocity v) e.Update your sketch of the motion of the particle to include: iv. The position of the particle at 3s V. The displacement Ay of the particle between 6-0 and-3s. vi. The velocity of the particle atに3s. E. Find the average velocity v of the particle between t, -0 and 1 3s Explain the meaning of the sign of the average velocity v) 1/4
