Question

Hey friends I need your help plz answer my question fast.

Answer 1

u = uxi + uyj = 10j, ux = 0 and uy = 10 m/s

a = axi + ayj = 8i + 2j, ax = 8 and ay = 2 m/s2

x = uxt + (1/2)axt2

16 = 8 t2/2

t = 2 sec         ... Ans

y = uyt + ayt2/2  = 10x2 + 2x22/2 = 24 m

vx = ux + axt = 16 m/s

vy = uy + ayt = 14 m/s  

Speed = √(vx2 + vy2) = 21.26 m/s
