Calculating Acceleration of a Rolling Wheelbarrow

CheersIn summary, a wheelbarrow starts from rest and travels down a hill with constant acceleration. Between 3 and 5 seconds, the displacement is 12m, and between 9 and 11 seconds, the displacement is 48m. The question is asking for the acceleration of the wheelbarrow.

A wheelbarrow is released from rest and, with constant acceleration, goes down a hill. Between 3seconds and 5seconds, the displacement is 12m, and between 9s and 11s, the displacement is 48m. What is the acceleration?

i'm not sure how to do a question where the intervals are not beside each other. should i set some equations equal to each other?

Thanks

What is acceleration?

Acceleration is the rate of change of an object's velocity over time. It is a measure of how quickly the object's speed is changing.

How do you calculate acceleration?

Acceleration can be calculated by dividing the change in velocity by the change in time. It is represented by the equation a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.

What is the difference between linear and angular acceleration?

Linear acceleration is the change in the object's velocity along a straight line, while angular acceleration is the change in the object's rotational speed. In the case of a rolling wheelbarrow, both types of acceleration can be observed.

How does the mass of the wheelbarrow affect its acceleration?

The mass of the wheelbarrow does not directly affect its acceleration, as acceleration is determined by the force applied to the wheelbarrow and its distribution. However, a heavier wheelbarrow may require more force to accelerate at the same rate as a lighter wheelbarrow.

What other factors can affect the acceleration of a rolling wheelbarrow?

The friction between the wheelbarrow's wheels and the ground, as well as the force and direction of the person pushing the wheelbarrow, can also affect its acceleration. Additionally, the shape and weight distribution of the wheelbarrow, as well as any obstacles or inclines in its path, can impact its acceleration.
