A rock is thrown vertically upward with a speed of 17.0 m/s from the roof of a building that is 70.0 m above the ground. Assume free fall. A) In how many seconds after being thrown does the rock strike the ground? B) What is the speed of the rock just before it strikes the ground?
A person pulls a 26kg suitcase using a rope attached to the suitcase at an angle of 28 degrees to the horizontal. The coefficient of static friction of the suitcase with the floor is 0.3 and the coefficient of kinetic friction is 0.20.
determine the value of IG. The support at B does not move while the measurement is taken. For the calculation, the horizontal location of G should be determined.
