Calculating Change in Velocity of an Object with Constant Acceleration
When an object moves along a straight path with a constant acceleration, we can calculate the change in velocity of the object in a given time period using the following formula:
Δv = a × t
where Δv is the change in velocity, a is the constant acceleration, and t is the time period.
Given Information
In this case, we are given that the object has a constant acceleration of 4m/s² and we need to calculate the change in velocity of the object in 5 seconds.
Calculating the Change in Velocity
Using the formula above, we can calculate the change in velocity of the object as follows:
Δv = 4m/s² × 5s
Δv = 20m/s
Therefore, the change in velocity of the object in 5 seconds is 20m/s.
Explanation
When an object moves with a constant acceleration, its velocity changes at a constant rate. This means that we can use the formula Δv = a × t to calculate the change in velocity over a given time period. In this case, we were given the constant acceleration of the object (4m/s²) and the time period (5 seconds). By plugging these values into the formula, we were able to calculate the change in velocity of the object over the given time period.
