Hi, i'm just practicing some SUVAT style questions as part of my revision and have a quick question. Here's an example, a ball is catapulted vertically upwards at 10m/s, find the time it takes to hit the ground.(Discount air resistance) I used S =0 U=10 m/s V=? A=-9.8 T=? Using v =u +at gave me a time of 1.02s however this is wrong. Is this because i've done this as one motion? Should I split it into to, ie find highest position then journey back down? Thanks Just to reiterate this isn't a homework question.
