Question

An E. coli bacterium can be modeled as a
0.50-um-diameter sphere that has the density of
water. Rotating flagella propel a bacterium through
40° C water with a force of 75 EN, where
1 fN=1 femtonewton = 10-15 N.
Part A
What is the bacterium's speed in μm/s?
Express your answer in micrometers per second.

You are working part-time for the GT Sports Media Complex, editing video for the women’s softball team. In one particular clip, a GT player hits a home run over the center field fence. The ball leaves the bat at a height of 4 ft, and crosses the outfield fence (220 ft away) at a height of 10 ft. Logs of the game indicate that the pitch was clocked at 68 mph as it reached the plate. Your frame-by-frame analysis of the 30-frame-per-second video indicate that the ball spent only a single frame in contact with tha bat, and another 126 frames travelling to the outfield fence. A quick internet seach tells you that a typical college softball weighs 0.4 lb. How many pounds of average force act on the ball during ocntact with the bat?
G=25
A steam catapult applies a very large force to supplement the engine thrust of a jet fighter as it takes off from an aircraft carrier. The jet has a mass of 3850 kg ad must reach its take off speed of 75 m/s at the end of the 208 m fight deck. What is the combined force of the catapult and engines?
A block is sliding along a frictionless surface at 11.1 m/s. The block slides down a hill. At the bottom of the hill, the block is sliding at 36.5 m/s. How tall (in meters) is the hill?
A commercial jet is coming in for landing. Just before it hits the runway it is moving 76m/s. Plane has a mass of 20,000kg. The runway is 1.6km long and the plane needs to stop before the end of the runway. How large is the braking force the airplane needs to stop safely?
An 96kg diver inhales to have a body density of 950 kg/m3, then swims to the bottom of a shallow sea (sea water density = 1024 kg/m3) and begins to float to the surface. What is his acceleration? (g=9.8 m/s2)
A physics student, in a stationary elevator, places a 240.0 g mass on an electronic balance. The student hits the elevator button and it begins to move upwards. While the elevator is moving, the student records this information Time = 0 to 3.0 sec the balance reads 278 grams Time = 3.0 - 12 sec the balance reads 240. grams Time = 12.0 to 15.0 sec the balance reads 192 gram How far up (in meters) did the elevator travel? Consider: UP to be (+), DOWN to be (-) and g =9.8 m/s2 . ROUND YOUR ANSWER TO A WHOLE NUMBER of meters (no decimal places) HINT: This problem requires finding THREE different displacements and adding them up! 2nd HINT: You will need to (A) use your equations of motion or (B) make a v-t graph to find those displacements!
What net force is required to make a 15 kg box move at a constant speed of 2.0 m/s.
A rock, in deep space, has a rocket thruster, with negligible mass, attached to it. The rocket causes a force of 3,300[N]. If the rock has a mass of 4.62×104[kg], what is the acceleration experienced by the rock, due to this force alone? Express your answer in terms of m/s2.
A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?
