Which physical unit represents acceleration in the british system o 40km, sw 0-120 miǚ o186000 m

foot per second squared  ft/s^2

Explanation:

The british unit are the following:

LengthLinch, foot, yard , rod, chain, furlong, mile

TimeTsecond, minute , hour, day

If AccelerationL / T^2 thefore the unit is foot/second^2

c

explanation:

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
