Answer:
acceleration is 1.59 m/s²
required % is 16.22 %
Explanation:
given data
radius = 63 m
speed = 10 m/s
to find out
acceleration of the car and acceleration due to gravity
solution
we know car is moving in circular path
so acceleration will be, a = [tex]\frac{v^2}{r}[/tex] .........1
put here value
a = [tex]\frac{10^2}{63}[/tex]
a = 1.59 m/s²
so acceleration is 1.59 m/s²
so acceleration due to gravity as a percentage is 9.8 m/s²
required % = [tex]\frac{1.59}{9.8}*100[/tex]
required % = 16.22 %
