Q: With the following two equations, find the value of :
. Mr F adds: => 0 = ut - 7gt^2.
The correct answer is . I'm getting an incorrect answer. Can someone do this question and see if they obtain the correct answer so I can compare with mine. Thanks in advance.
Substitute ut from (1) into (2), take g = 9.8 and solve for t (keeping only the positive value): t = 2.31 seconds.
Substitute t into (1) and solve for u: u = 159.1 metres.
Could you completely specify the problem (as in originally how it was stated)?
I think that will help
