Answer 1

Answer:

we have to find the LCM of the three no's

so LCM is

10-2x5

18-2x3x3

15-5x3

LCM is 450

Answer 2

Answer:

220m - 44.5m = 175.5m = V₀ (8) + a (8)² /2

175.5 = 8V₀ + 32a ↔ equation (1)

i) d = 220m - x = 220m - 76.6m = 143.4

ii) 143.4 = V₀t₂ + at₂² / 2

143.4 = V₀ (6.9) + a(6.9)² / 2
