16 As shown in Figure (5), block A, with a mass of 10 kg, slides down the slope from stationary to hit block B, with a mass of 5 kg. Block A travels 5 m immediately before hitting block B. The sliding friction coefficient between the blocks and the slope is = 0.3. O-x-y is a sta- tionary inertial reference frame. The slope angle, 0-45°. What is the speed of block A immediately before hitting block B with respect to...

How do you solve this problem without the work/energy
method?
-0.3m- hec The block has a mass of 0.8 kg and moves within the smooth vertical slot. If it starts from rest when the attached spring is in the unstretched position at A, determine the constant vertical force F which must be applied to the cord so that the block attains a speed vg = 2.5 m/s when it reaches B; $ = 0.15 m. Neglect the size and mass...

Learning Goal:
To use the principle of work and energy to determine
characteristics of a mass being pulled up an incline and determine
the power that must be supplied to the system when the efficiency
of the input system is considered.
As shown, a 62 kg crate is pulled up a θ = 65 ∘incline by a
pulley and motor system. Initially at rest, the crate is pulled s =
2.9 m up along the incline. Undergoing constant acceleration, the...
