Best ResponseYou've already chosen the best response.0So x = 0.5* 15 * 8 = 60m

Best ResponseYou've already chosen the best response.1Well, you have initial velocity = u = 54 kmph = 54 x (5/18) m/sec = 15 m/sec Final velocity = v = 0 Time = 8 seconds. Use Newton Unkle's equation # 1 > \( a = \frac{vu}{t}\), and fond out the deceleration 'a'. Then, use \(v^2  u^2 = 2as\) to find out the distance covered, i.e. 's'.

Best ResponseYou've already chosen the best response.1(Note of precaution: Newton's equations are only valid for uniformlinear motion, as you may know.)

Best ResponseYou've already chosen the best response.1sry... use \[x=\frac{v+u}{2} \times t\]

Best ResponseYou've already chosen the best response.1where v is final speed=0 u is initial speed=15 and t=8

Best ResponseYou've already chosen the best response.1Yeah, using the average velocity funda is good actually, @King
