sorry I am still not following, would i be able to send you the excel spreadsheet i have so far so you can take a look at what I've done? thanks

Theb bouncing bomb was designed to explode at a depth of 9m below the surface. The dam itself, had the dimensions shown below. 7.6m wide at top 39.6m wide at bottom 34m height 135x10^6m^3 of water behind dam bomb sinks and explodes against wall at 9m depth If the explosion developed...

so to create this graph i would use this equation to find the pressure of 100kn and at each 1m and add the pressure of the water using pressure=water density*gravity*depth?, would it make any difference to the 2m of the dam protruding out of the water or the changing thickness of the dam? thanks

is it just force*area?

so pe=176.4j before being dropped and ke=176.4j at impact, how would it be rearranged to find out the new velocity? (ive never used these formulae before so sorry if I am slow) is the co efficient of restitution used here at all? thanks

is it possible to work out the potential energy without the mass of the object? would there be another way to work out the height of the next bounce?

Question is: plane flies at a speed of 100m/s at a height of 18m above water plot the trajectory from release to first impact point, in intervals of 0.2m managed this and have plotted the trajectory, with relevant velocities and resultant but the next part asks: "At each bounce the...

m studying civil engineering and trying to research how a bomb would affect a dam, but i know little about physics so could anyone help with this problem? dam has dimensions 7.6m wide at the top, 39.6m wide at the bottom and 34m tall, water level is 2m from top of the dam. 135*10^6 cubic...
