Speed is constant.
Speed has direction and velocity.
Speed is measured over time.
Answers
The statement about speed and/or velocity which is true is: Velocity has both speed and direction.
Velocity refers to the rate of change in displacement (distance) with time. Velocity is a vector quantity and this simply means that, it has both magnitude (speed) and direction.
Mathematically, velocity is given by the formula;
On a related note, speed is a scalar quantity because it has magnitude but no direction.
However, both speed and velocity are measured in meters per seconds.
In conclusion, the relationship between speed and velocity is that velocity has both speed and direction.

W = Fd
where:
F = force exerted = ma
d = distance traveled
m = mass of object
a = acceleration
Acceleration is equivalent to the gravitational constant (9.81 m/s^2) if the force exerted has a vertical direction such as lifting.
W = Fd = mad = 63(9.81)(7) = 4326.21 Joules
Now that we have work, we can calculate power.
P = W/t = 4325.21 J / 5 seconds = 865.242 J/s or watts
Convert watts to horsepower (1 hp = 745.7 watts)
P = 865.242 watts (1hp/745.7 watts) = 1.16 hp
work = mgh
power = mgh/t = 63•9.8•7/5 = 864 watts
1 HP = 746 watts
so that is 834/746 = 1.2 HP

Unbalanced force causes an object to change its motion.
Answer: Option A
Explanation:
A force can be explained as push or a pull that has the tendency to change the velocity of a mass.
The force that makes any change in the movement of an object or body is known to be an unbalanced force. These forces are not equal and opposite. When an object is placed in a rest position and when unbalanced force acts on it, this will not make the object to move.
Example: Force applied against the ball.
The forces whose size is equal and opposite in their direction are known as balanced force. These forces will not make any change in motion of a body. When an object is placed in a rest position and when balance force acts on it, this will not make the object to move.
Example: Pushing against a wall.
Answer:
I believe it is A. Unbalanced.
