ac = v^2 / R
15 cos 30° = V^2 / 2.5
V^2 = 32.73
V = 5.7 m/sec.
15 cos 30° = V^2 / 2.5
V^2 = 32.73
V = 5.7 m/sec.

what is ac
acceleration h
ok thanks and how u got directly 32.73 , 5.7
umm calculate yr
15*2.5*cos 30°
I am not get calculation sorry can u brief explain
ok
kk sure .....
ka ho

Answer:
15cos30=v^2/R
Therefore, v^2=2.5×15×root3/2
V =5.7 m/s
