The difference between the parts of the plot with positive slope and the parts with negative slope can be found below.
<h3>What is a slope?</h3>
A slope in a graph is the ratio of the vertical and horizontal distances between two points on a line. Slope shows both steepness and direction of values.
A slope can either be positive or negative depending on the relationship between the variables being plotted.
A positive slope means that the variable are directly related while the negative slope means that two variables are negatively related.
A positive slope further means that the line moves upward when going from left to right on the graph while with the negative slope, the line moves down when going from left to right.

The force that must be exerted on the outside wheel to lift the anchor at constant speed is 6.925 x 10⁵ N.
<h3>Force exerted outside the wheel</h3>
The force exerted on the outside of the wheel can be determined by applying the principle of conservation of angular momentum as shown below.
∑τ = 0
- Let the distance traveled by the load = 1.5 m
- Let the radius of the wheel or position of the force = 0.45 m
∑τ = R(mg) - r(F)
rF = R(mg)
0.45F = 1.5(21,200 x 9.8)
F = 6.925 x 10⁵ N.
Thus, the force that must be exerted on the outside wheel to lift the anchor at constant speed is 6.925 x 10⁵ N.

Answer:
16.96 m/s
Explanation:
It is the case of projectile motion in which the projectile fires from the ground and again it hit the ground.
The angle of projection is 32 degree and the velocity of projection is 20 m/s
he velocity at the maximum height is equal to the horizontal component of velocity which always remains constant as there is no acceleration along x axis.
Velocity at the highest point = u Cos 32 = 20 x Cos 32 = 16.96 m/s
