average speed is 10.3kmh 15km/h for ten hours is 150km 20km/h for 6 hours is 120km 10km/h for 5 hours is 50km 10hrs at rest 150+120+50=320km in 31hrs Speed average=total distance travelled/time taken 320/31= Average speed of the ship is 10.3km/h currently trying to work out th...

This is what i did but i totally could of got it so wrong. this assignment is way harder then i thought it would be :) Landing craft mass=12000kg d=160m above moon surface Vi=15m/s g on earth=9.81m/s g on moon g/6 g on moon=1.635m/s Vf=0m/s Needed thrust=?? Assuming the crafts...
Physics review
In this example, sound waves are created in a tube. The tube is partially filled with water and the level of water is adjusted in the tube until there is a standing wave. Draw the lowest frequency standing wave for the two water levels in the drawing. The drawing has two tubes...

Two cars have identical horns, each emitting a frequency of f= 395 hz. One of the cars is moving with a speed of 12 m/s toward a bystander waiting at a corner, and the other car is parked. The speed of sound is 343 m/s. what is the beat frequency heard by the bystander?
Physics review
Add the accel+radius+ mass? I was a little unclear I need the moment of inertia for each individual object. Does what you said still apply?
Physics review
So I've already found/ was given the radius, hanging mass, and acceleration for three objects but I need to find the moment of inertia using all those three. What equation do I use or how do I incorporate all of them to find the moment of inertia?
Physics
Should the 1.4 that you used be 1.1?
Physics
Why does it have to be zero?
