To solve the exercise it is necessary to apply the concepts given in Newton's second law and the equations of motion description.
Let's start by defining acceleration based on speed and time, that is
On the other hand according to Newton's second law we have to
F=ma
where
m= Mass
a = Acceleration
Replacing the value of acceleration in this equation we have
Substituting with our values we have
Re-arrange to find v
Therefore the speed of the glider is 2m/s
Answer:
False
Explanation:
the total distance of a moving body is always positive
Distance is the total distance between any two points
Answer:
The gravitational force on the elevator = 4500N
Explanation:
The given parameters are;
The force applied by the elevator, F = 4500 N
The acceleration of the elevator = Not accelerating
From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;
F = W + Mass of elevator × Acceleration of elevator
∴ F = W + Mass of elevator × 0 = W
F = 4500 N = W
The net force on the elevator is F - W = 0
The gravitational force on the elevator = W = 4500N.
Measurements in physics is important because it enables people to argue using mathematics where numbers can be used to represent knowledge in a convenient manner when we show and communicate about a phenomenon.
Explanation:
When a physician is able to measure a phenomenon, then we get a foundation of understanding a lot of things in our universe.Measuring these things will help know how to use them in various applications.

The most effective way to prevent beach erosion is to replant mangrove trees, seaweeds and seagrass. The strategic planting of vegetation can be used to help control erosion. The roots of these plants help to anchor the sand and ensure that it is not carried off in erosion. This is why many areas plant seagrass and build marshes along coasts to prevent erosion.
