I'm so confused can someone help??
The driver of a pickup truck going 120 km/h applies the brakes, giving the truck a uniform deceleration of 5.00 m/s2 while it travels 35.0 m. How much time has elapsed?

Best ResponseYou've already chosen the best response.2Given: Vi = 120Km/hr, a = 5m/sec^2, dh = 35m Variables not given: Vf Required: t USe the d= Vi X t + 1/2(a X t^2) and solve for "t"

Best ResponseYou've already chosen the best response.0can you slow down and explain some of these? I don't really understand. like in the 2nd photo where are you getting the 5 you're diving by?

Best ResponseYou've already chosen the best response.2Always remember this trick....identify your variables... see what's given to you and what isn't and what is required..... in this case. They gave us the acceleration, initial velocity and horizontal distance. but they didn't tell us the final velocity and asked you to find the time...this is where you need to use a little trick, use the formula for which the variable isn't given...

Best ResponseYou've already chosen the best response.2and solve for the "T". you should get a quadratics expression.....t = m/sec^2T^2 + m/secT horizontal distance(35m) use the quadratics formula to solve for time....
