Force is found by multiplying mass (kg) and acceleration (m/s^2), so the metric unit of force is kg*m/s^2 or N (newtons)
The normal force is always perpendicular to the surface. So it would be straight to the left of the wall
<span>In order for
an object to accelerate, a <u>force</u> must be applied. It follows Newton’s second
law of motion where it states that a body at rest remains at rest unless a
force is acted upon it. When you move an object, you are exerting a force onto
it. By exerting a force on the object, you are actually displacing it from its
initial position. You cannot apply force to the object without altering its
position. Keep in mind that when you exert work, you are exerting energy too. </span>
Answer:
15km
Explanation:
Given parameters:
Average speed = 60km/hr
Time taken = 15min
Unknown:
Distance = ?
Solution:
The distance traveled can de derived using the expression below;
Distance = Average speed x time taken
Now let us convert the time to hr;
60min = 1hr
15min = 
= 0.25hr
Distance = 60km/hr x 0.25hr = 15km
