A man with mass m1 = 54 kg stands at the left end of a uniform boat with mass m2 = 174 kg and a length L = 2.6 m. Let the origin of our coordinate system be the man%u2019s original location as shown in the drawing. Assume there is no friction or drag between the boat and water.
1 - After walking to the right edge of the boat, how far has the man moved from his original location? (What is his new location?) answer should be 1.98 m
2 - After the man walks to the right edge of the boat, what is the new location the center of the boat?
3 - Now the man walks to the very center of the boat. At what location does the man end up?
An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is ? = 1.90 10-7 C/m2, and the plates are separated by a distance of 1.5 10-2 m. How fast is the electron moving just bef..
