How do you do part b?
An object falls from the top of a building. An office worker sees the object fall past a window 2 m high in 1 5 s. Assume that air resistance is negligible and use g = 10 m/s^2 . Let y be the height of the object above the bottom of the window at time t.
(a) Show that y = H...
Hey how do I do part c?
a) Prove that the range on a horizontal plane of a particle projected upwards at an angle A to the plane with velocity V meters per second is (V²sin 2A)/g meters
A garden sprinkler sprays water symmetrically about its vertical axis at a constant speed of V meters per...
A boat has a speed relative to the water at 3m/s. The boat points 35 degrees to the shore, moving upstream on a river flowing 0.75m/s. How much time does it take for the boat to reach the opposite shore if it the river is 50m wide?
I know how to do question a but how do I do question b? I think Im pretty close - my integration result looks pretty similar to what ive proved but i dont know what to sub in; subbing in -1 or 1 should work but it doesnt work for me
so i can do question A by doing LHS- RHS and then doing 2 cases where a>b and a<b so show LHS - RHS >0 ; is there and alternative solution?
and for B and C, I have absolutely no clue.; for B i think you have to add multiple inequalities but i am not sure what inequalities.
I seem to really struggle with the english ext common module where you generally have to write a narrative in the perspective of the set character... so does anyone have any tips? Also does anyone have any resources for english ext; like trial papers from other schools?
