Homework Statement Hi i have a question I've been doing and need to know if i am completely wrong (or not) any help woul be really appreciated. A fairground ride ends with the car moving up aramp at a slope of 20degrees to the horizontal Homework Equations a)The car carrying its maximum...

Hello, i have just had a quick go at the first question i posted and is the answer 221.6ms-^1. I just did 300ms-^1sin90-g x t is this correct? Thanks, Chris.

oh ok what is the v0 bit in that equation horizontal velocity? and for question 2 part a you said i was wrong to multiply the time of 4.23 seconds by two, how come? i thought this would be the max height reached so i thought i ha to multiply by 2 to get the total time of flight. Could you...

okat 4.23 sec the vert velocity is 0 as the object is at max height so at 8 sec i work out that the vert velocity = 36.946ms^1 (3.77 secs after attaing max height?) is this correct? Thankyou, Chis.

sorry didn't mean to put the g=78.4 bit that would be the vertical velocity at 8.0sec and the horizontal is 90.6... so whatdo i do with that i thought i would find the resultant and then find the angle using trig? on the time should i have just left a 4.32sec? i thought it would be timesd by 2...

hello, well the horizontal velocity is constant and g act downwards so only effects the vertical motion? i take it 163ms^1 is wrong. sorry for not putting my working for the second question. Here it is for question 2.. a) V(horiz) = cos25degree x 100ms^1 so V(horiz) =90.6307787ms^1...

Hello, i have a few questions i am doing and am wondering if someone would be kind enough to check i am doing them correctly:rolleyes: First question is.. A shot is fired horizontally at a target 20m away and it is notice3d that the bullet hits a point 7.5cm below the target aimed at. What...
