Problem #2 Collar A starts from rest and moves downward with a constant acceleration of 7 ins. Collar B moves upward with a constant acceleration and has an initial velocity of 8 ins. Knowing that collar B moves through 20 inches in the first 2 seconds, determine the following: (a) Accelerations of B and C (b) The time at which velocity of C is zero (c) The distance that C moves in the time determined in part b.

A particle starts from rest at x = -1.8 m and moves
along the x-axis with the velocity history shown. Plot the
corresponding acceleration and the displacement histories for the
2.0 seconds. Find the time t when the particle crosses the
origin. After you have the plots, answer the questions.

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.

A 612-kg elevator starts from rest and moves upward for 4.50 s with constant acceleration until it reaches its cruising speed, 1.64 m/s. (a) What is the average power of the elevator motor during this period? hp (b) How does this amount of power compare with its power during an upward trip with constant speed? (Give the power during an upward trip with constant speed.) hp

A 500 kg elevator starts from rest. It moves upward for 2.50 s with constant acceleration until it reaches its cruising speed, 1.75 m/s. a.) What is the average power of the elevator motor during this period? b.) How does this power compare with the motor power when the elevator moves at its cruising speed?

008 10.0 points An elevator starts from rest with a constant upward acceleration and moves 1 m in the first 1.8 s. A passenger in the elevator is holding a 4.6 kg bundle at the end of a vertical cord. What is the tension in the cord as the ele- vator accelerates? The acceleration of gravity is 9.8 m/s. Answer in units of N.
