An arrow is shot at an angle of above the horizontal. The arrow hits a tree at an angle 45 degrees horizontal distance D = 220 away, at the same height above the ground as it was shot. Use g = 9.8 for the magnitude of the acceleration due to gravity. Plea...

A ball is thrown toward a cliff of height h with a speed of 27m/s and an angle of 60 degrees above horizontal. It lands on the edge of the cliff 3.0s later. What is the height of the cliff? What is the maximum height of the ball? What is the ball's impact...

A turbine spinning with angular velocity w_0 rad/sec comes to a halt in T seconds. Find an expression for the angle delta theta through which the turbine turns while stopping.

A turbine is spinning at 3600rpm . Friction in the bearings is so low that it takes 11min to coast to a stop. How many revolutions does the turbine make while stopping?

a student wants to perform an experiment to study the relationship between the temerature and pressure of an enclosed gas in one or two sentances describe two assumptions that must be made in performing this experiment

H2(g) + 12(g) + 2H1(g) A student makes the following statements: - Hydrogen always has the same oxidation number, so it has an oxidation number of +1 in both the reactant H2 and product Hi. - Iodine is in Group VIlA, so it has an oxidation number of -1 in...
