to save time. I found the time to be 2.7778 seconds which is verifed. Trying to answer the last line NOTE IHIS IS a multi-part question. Unce an answer is submitted, you will De unable to return to this part Collar A starts from rest at t- 0 and moves upward with a constant acceleration of 3.6 in/s with a constant velocity of 20 in./s. Collar B moves downward Determine the corresponding position of block C The corresponding position of...
An elevator starts from rest with a constant upward acceleration. It moves 2.0 meters in the first 0.6 seconds. A passenger in the elevator is holding a 3 kg package by a vertical string. What is the tension in the string during the acceleration process? [Hint: remember Newton's 3rd law]
PB#1 : A train starts from rest (at position zero) and moves with constant acceleration. On first observation, the velocity is 20 m/s, and 80 s later the velocity is 60 m/s. At 80 s, calculate the position at t = 20m/s, average velocity, and constant acceleration over the interval.

Find: a) The average speed, V, for the first second (Vad/t b) The initial speed, V, If Vav (v vV2, what is vr, the final speed after 1 sec? In the next second from t1s to t 2s, the ball rolls 18 cm. Find c) The average speed, Vav, for the interval from 1-2 seconds (a d/t) d) The...
A speedboat starts from rest with a constant acceleration of +1.50 m/s2. After 4.00 seconds, its acceleration changes to +1.00 m/s2. After another 5.00 seconds, its acceleration changes to zero and the boat travels with constant velocity for a further 10.0 seconds. The boat then slows down and stops by accelerating at -2.00 m/s2. 1. Calculate the velocity and displacement of the boat at t = 4.00 seconds. 2. Calculate the velocity and displacement of the boat at t =...
