Initial velocity of hovercraft = vih= 0 m/s ……(It’s correct)
Initial position of speederbike = x0s = 68*2 = 136 m
a) xfh = xfs
x0h+vih*t +1/2*ah*t^2 = x0s+vis*t
0+0*t -1/2*4*t^2 = 136+86*t => t= 35.9s
xfh=xfs = 2577.2m
b) The maximum distance = 68.0*2.0 = 136 m
A galactic police officer's hovercraft is parked at a speed trap when a speeder bike flies...
You are arguing over a cell phone while trailing an unmarked police car by 36 m. Both your car and the police car are traveling at 100 km/h. Your argument diverts your attention from the police car for 2.0 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 2.0 s, the police officer begins emergency braking at 5 m/s2. (a) What is the separation between the two cars...
Assume, unless otherwise specified, that all numbers have at least 3 significant figures. and please circle your answers. You may work together, but make sure that you are working-not just watching. Peter Policeman is sitting by the side of the road when Sammy Speeder flies by in his Tesla Model S at 100 mph. Peter takes one second to react before jamming on his accelerator giving his Ford Crown Victoria Police Interceptor an acceleration of 3.5 m/s^2. Assume the car...
