A 500 kg rocket sled is sitting at rest at the bottom of a ramp (i.e., ground level, y = 0 m).  It has just enough fuel to accelerate along the length of the ramp.  The sled is propelled along a 25 m long ramp of angle θ = 30˚ with a constant acceleration.   When it leaves the ramp, the engine cuts off and it has a speed of 948.7 m/s. Once the sled leaves the ramp, it travels as a projectile through the air.   a) Find the height of the ramp. height = b) Find the velocity vector of the sled at the instant it leave the ramp.  Give the velocity in terms of the x- and y- coordinate system shown. v = +   c) What is the thrust provided by the rocket engine? Thrust = d) What is the total time the sled is in the air? Time of Flight = e) When the sled lands, how far has it traveled horizontally from the end of the ramp? xdistance =

 Which antimicrobial method will you choose if you wanted to destroy all microorganisms including bacterial endospores the quickest and most definitively?    

All of these are true of Frederick I’s reforms EXCEPT

To boxes are arranged as shown in the figure below.  Box 1 has a mass of 7 kg and box 2 has a mass of 5 kg.  The string connecting the two boxes passes of the edge of a 0.5 kg solid pulley with a radius of 7 cm.  The coefficient of friction on the incline is 0.15.  Determine the magnitude of the acceleration of the masses.   a = m/s2

Rulers who sought to gather into their own hands command of the state’s armed forces, control over its legal system, and the right to collect and spend the state’s financial resources at will were called

Which of the following is a reason why transient microbiota have difficulty colonizing the human body?

The oxidizing agent in a chemical reaction is the substance that is being reduced.

People who wash their hands frequently during cold season typically have fewer colds than those who do not. This observation suggests cold viruses can be transmitted by
