Answer:
b. -1.5 m/s²
Explanation:
Given the following data;
Initial velocity = 15m/s
Time = 10 seconds.
Since the car came to rest, final velocity = 0m/s
To find acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of final speed from the initial speed all over time.
Mathematically, acceleration is given by the equation;
Where,
a is acceleration measured in 
v and u is initial and final speed respectively, measured in 
t is time measured in seconds.
Substituting into the equation, we have;
Acceleration = -1.5 m/s²
Answer:
smaller acceleration, so lower change in velocity
Explanation:
To answer this question we examine the equation that relates mass with force and with acceleration: 
.
Since we want to know what happens to the acceleration, we solve for it in the equation: 
Notice that we are asked what happens when the force applied is the same, but now it is applied in an object with more mass (M).
We therefore would have to compare our initial form:
with the new one: 
wher the denominator is a larger quantity, therefore making our division/quotient smaller. Then, we conclude that the acceleration will be smaller, and therefore the change in velocity of the object will be lower.
The answer is "C" because the equator is closest to the sun, because the sun's rays hits the earth surface at the higher angel at the equator and also the sun is directly overhead the equator.

The formula for final velocity is Speed= distance/time (s=d/t)
Velocity is another word for speed.
