Mechanical EngineeringMechanical Engineering? Block C is moving downward with a velocity of 5 m/s^2, which is decreasing at a rate of 1 m/s^2, while block A is moving upward with a velocity of 8 m/s^2, which is decreasing at a rate of 3 m/s^2. Determine the velocity and acceleration of block B at this instant.
An electron moves at speed 5.6 x 106 m/s toward the velocity selector shown in (Figure 1). A 0.12-T magnetic field points into the paper. Part A Determine the magnitude of the magnetic force that the magnetic field exerts on the electron. Part B Determine the direction of the magnetic force that the magnetic field exerts on the electron. upward downward Part C What E field magnitude is required so that the electric force exerted on the electron is equal in magnitude and opposite in direction to the...

2:20 AT&T NIGER A paratrooper is initially falling downward at a speed of 27.5 m/s before her parachute opens. When it opens, she experiences an upward instantaneous acceleration of 75.0 m/s2. Part If this acceleration remained constant, how much time would be required to reduce the paratrooper's speed to a safe 5.75 m/s? (Actually the acceleration is not constant in this case, but the equations of constant acceleration provide an easy estimate.) peringe 2:20 AT&T Part How far does the...
Chapter 2, Problem 2/180 The velocity of A is 1.5 m/s downward, the velocity of B is 3.2 m/s upward, and the velocity of D is 3.3 m/s downward. Find the velocity of C. The velocity of C is positive if downward, negative if upward. D A с B Answer: Vc = m/s the tolerance is +/-2%
