Answer: Option D
We know that speed is defined as the derivative of the position with respect to time. The derivative shows the slope changes that occur in the graph of the function shown.
Observe the attached image.
Notice that at the beginning the graph resembles a line whose slope is constant. This means that during this time interval (t1) the speed is approximately constant and greater than zero. Then we observe a time interval during which the function is approximately horizontal, parallel to the time axis. In this interval (t2) the slope is approximately 0. This means that in this interval the velocity is approximately 0. Finally, the graph has a positive and large slope. This means that during the last time interval (t3) the speed increases. Therefore the correct option is D.
D. The velocity decreases, then increases.

Explanation:
according to newton's second law of motion,
F = MA
where F is the resultant force
m is the mass
a = acceleration
so suppose the mass of the bowling ball is 10 kg
and the mass of golf ball is 1 kg
and the force applied on both of them is 5 N
substitute the values in the formula
for the bowling ball
5 = 10 x a
a = 0.5 ms²
for the golf ball
5 = 1 x a
a = 5 ms²
so which accelerated more the golf ball right?
so last option is the answer

Answer:
Density = 1.14 kg/mm³
Explanation:
Given the following data;
Volume = 2.10 cm³ to mm = 2.10 * 10 = 21 mm³
Mass = 23.94kg
To find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
Substituting into the equation, we have;
Density = 1.14 kg/mm³
