What is the potential difference between x(i)=10cm and x(f)=30cm in the uniform electric field E(x)=1000 V/min? Please show work so I can understand how to solve it.
An aircraft weighing 819 N is accelerated at 11.7 m/s2 for 5 seconds, at which time the aircraft launches. What is the force required to launch the aircraft
A particle moves along the x-axis. Its position varies with time and is given by equation x =-6t + 3t^2 where x is in metres and t is in seconds. Sketch the position time graph for the particle between 0s and 4s.
A 96 kg man walks along a 50 kg horizontal plank which is 4 m long. The plank is attached to a hinge mounted to one wall, and the far end is supported by a vertical wire which is attached to an anchor in the ceiling. The wire can just barely support ..
A bucket filled with water has a mass of 23 kg and is attached to a rope, which in turn, is wound around a 0.050-m radius cylinder at the top of a well. Illustrate what torque does the weight of water and bucket produce on the cylinder if the cyli..
