is the answer 40% ? (0.5x 0.005) x 40^2

sorry but you have to dumb this down I'm doing GCSEs and i don't understand what you mean by the Vs, i also have no idea why it slows down

i've finished the first part (a) i can't do b and c for b i think because it already has reached it's fastest speed it must slow down from then on. what's the best way to word this? c. for this question i think it's o.5(0.005) x velocity^2 but i don't know how to work out velocity i...

for b i think because it already has reached it's fastest speed it must slow down from then on. what's the best way to word this? c. for this question i think it's o.5(0.005) x velocity^2 but i don't know how to work out velocity i know it's v=d/t.

when a gun is fired a very large force acts on the bullet for a very short time. formula that's given: force x time = change in momentum (kg m/s) an average force of 4000 acts for 0.01 seconds on a bullet of 50g mass. DONE THIS PART b. the bullet is fired...

did i get the question right?

did i get the question right?

is the answer 240/35?

so it's 240/35 ? = 6.9m/s is that the final answer and it's not squared?

3 m/s is it squared but how can that be the answer when it's already written in the question?

ok thanks so what would i have to do to find how fast the boat moved in the opposite direction?

you are very kind for helping me. 80kg 240 kg m/s 105 kg m/s 35kg no idea for velocity i know formula is f=d/t but you aren't given time or distance.

how can it be 3m/s^2 because that ids already given in the question. i think i remeber my teacher saying that it's: 80 + 35= 115 115 x 3 = 375 375/35 = 1.3...m/s is that correct?

i still don't understand i don't understand what formula to use as well.
