a 275-kilogram object starts from rest and accelerates on level ground up to a speed of
41 meters per second over 49.3 meters. it continues at that speed for another 15
meters. at the end of the 15 meters, the object is launched forward at a 37Ā° angle.
a. how much time does it take for the object to reach its final velocity?
b. how much force did the object apply in order to reach that final speed?
c. what are the maximum range and height of the object when it is launched?
d. at what angle would the object have to be launched to reach a height of 50
meters above the ground at the same initial velocity?
e. describe a realistic scenario in which this might happen.

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
