Question

a body with an initial velocity of 18km.hr accelerates uniformly at the rate of 9cm/s over a distance of 200m , calculate acceleration in m/s and final velocity in m/s

don't try to g00gle,not available!

Answer 1

Answer:

vₒ = 18 km/hr = 18000/3600 = 5 m/s.

a = 9 cm/s² = 0.09 m/s².

s =(v² - vₒ²)/2•a.

v = sqrt (vₒ² +2•a•s) = sqrt(25 +2•0.09•200) =7.81 m/s.
