(d) is increasing its velocity by 2.0 m/s every second.
An acceleration of 2 m/s² means that the object is is increasing its velocity by 2.0 m/s every second.
<h3>What is an acceleration?</h3>
The rate at which an object's velocity changes over a predetermined period of time is referred to as its acceleration. Acceleration is mathematically defined as an object's change in velocity divided by the amount of time it took for that change to occur.
The positive sign of the acceleration denotes a change in velocity that is positive and growing, whereas the negative sign denotes a change in velocity that is decreasing.
Consequently, an acceleration of 2 m/s² indicates that the object's velocity is increasing by 2 m/s every second.

Explanation:
Let's assume that the x-axis is aligned with the incline and the positive direction is up the incline. We can then apply Newton's 2nd law as follows:
Note that the net force is zero because the block is moving with a constant speed when the angle of the incline is set at Solving for the angle, we get

Answer:
v = 11 m/s
Explanation:
Given tha,
Initial speed, u = 5 m/s
Acceleration, a = 1.2 m/s²
Time, t = 5 s
We need to find the final speed of the boat during this time. Let it is v. Using first equation of motion as follows :
v = u +at
Putting all the values, we get :
v = 5 + 1.2(5)
v = 11 m/s
So, the final speed of the boat is 11 m/s. Hence, the correct option is (c).
