Question

The picture below shows a child (small brown circle) from above on a playground ride (large blue circle) that spins horizontally.
The red arrows show that direction of rotation of the ride.
The ride is NOT rotating at constant speed, but is slowing down.
Which of the following arrows best represents the direction of the acceleration of the child at the location in the picture?

• A. $\to$
• B. $\searrow$
• C. $\uparrow$
• D. $\nearrow$
• E. $\downarrow$

Answer 1

The correct option is A $\to$

Since the speed of child is decreasing at the moment, the acceleration is taking place in direction opposite to that of his motion, that is, acceleration is towards right.

There is no acceleration in vertical direction since the child remains stationary at the point relative to the ride.
