it is actually deceleration a
uzing v²= u²+2as where a is acceleration s is distance v is final speed and u is the initial speed
5²= 10²+2a(1600)
25=100+3200a
25-100=3200a
-75=3200a
a= -75/3200
=-0.0234m/s²
why the negative sign. it.shows that.the car is slowing down gradually. so the deceleration is 0.0234m/s²
Why do teachers want to know this outta us xc
4.2 km 1 mile 5,280 ft 22,176
* ---------- * ----------- = ----------- = 13,782.5 feet
1.609 km 1 mile 1.609
Using the conversion factors and setting the problem up so that you have km on top and bottom (so that they will cancel), miles on top and bottom (so that they will cancel), your answer will be left in feet.
Multiply across the numerator, then across then denominator. Finally simplify the fraction at the end.
