<span>This is the visual lead. This is the length of time and distance that a person should be scanning the road in front of them to see if any hazards are upcoming. Depending on the setting (urban vs. rural), this could be as few as 15 seconds' travel distance in front up to almost 30 seconds' distance in front on highway conditions.</span>
The wall will push back with an equal and opposite force, as defined by Newton's Third Law, so the wall will exert -200 N of force
Answer:
-3.5m/s²
Explanation:
Given
Initial Velocity, u = 30m/s
Final Velocity, v = 23m/s
Time, t = 2.0s
Required
Determine the magnitude of acceleration
This is calculated using first equation of motion.
v = u + at
Substitute values for v, u and t
23 = 30 + a * 2.0
23 = 30 + 2.0a
23 - 30 = 2.0a
-7 =2.0a
Solve for a
a = -7 ÷ 2.0
a = -3.5m/s²
Answer:
Explanation:
Potential energy is the energy stored within an object, due to the object's position, arrangement or state
