Question
A small car of mass m and a large car of mass 4m drive along a highway at constant speed. They approach a curve of radius R. Both cars maintain the same acceleration a as they travel around the curve. How does the speed of the small car vS compare to the speed of the large car vL as they round the curve

Answer:
Explanation:
Given that we have two cars
First car has mass =m
Second car has mass = 4m
They are driving at constant speed
Given that the radius of curve is R
Both cars maintain the same acceleration.
Let velocity of small car be vS
Velocity of big car be vL
From centripetal acceleration
a=V²/R
V²=aR
Then since both car have the same accelerating and bashing through the same curve of radius R
Then, We can say, V² is constant
vL² = vS²
Then taking square root of both side
vL=vS
