Answer:
2.572 m/s²
Explanation:
Convert the given initial velocity and final velocity rates to m/s:
- 65 km/h → 18.0556 m/s
- 35 km/h → 9.72222 m/s
The motorboat's displacement is 45 m during this time.
We are trying to find the acceleration of the boat.
We have the variables v₀, v, a, and Δx. Find the constant acceleration equation that contains all four of these variables.
Substitute the known values into the equation.
- (9.72222)² = (18.0556)² + 2a(45)
- 94.52156173 = 326.0046914 + 90a
- -231.4831296 = 90a
- a = -2.572
The magnitude of the boat's acceleration is |-2.572| = 2.572 m/s².
I believe it would be A, (B) just because a women trains doesn't mean she'll bulk, the may become thinner, or more tone. No to C because You have to change up and make workouts more difficult to help improve your body, and no to D because a workout doesn't have to be strenuous, you can be careful and not crazy about working out and still help your body. hope this helped
We can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.
<h3>How we can calculate the thickness using screw gauge?</h3>
We can determine the width/thickness of a coin by using a screw gauge because screw gauge is an instrument that measures thickness of an object that are very thin. First we can placed the coin in between the teeth of the gauge and then move the gauge until the coin can be held tightly. After that note the reading on the scale.
So we can conclude that we can calculate the width/thickness of a coin using a screw gauge by placing it in between the teeth of the gauge.
