A 55.0 kg crate is being pulled down a 20.0 $^{\circ}$^?  incline by a rope(acting parallel with the incline surface). If it is accelerating downwards at 1.50m/s $^2$²  and the force of the kinetic friction is 152 N then what is the tension of the rope?

An  athlete jumped a pole vault that was over 2 m high . Her horizontal distance was 5m. What was her initial speed?

800 J pf work are done pushing a 40.0 kg crate 6.0 m along a horizontal surface with u = 0.30. If the crate started at rest, what speed does it reach

(21.7kg) (3.2m) (1.4m/s^2)

365 km/day to m/s

2.31 x 10^8 g/cm^3 to kg/m^3

(333kg*m/s^2) (2.5x10^5m)

Rearrange to solve for the variable G

F = Gm1-m2 / R^2

Does the mass of a ball matter when determining the time it takes to fall? Why or why not? 

A baseball is thrown with a velocity of 27.0m/s 35 degrees. What are the components of the balls initial velocity? How high and how far will it travel?
