Hope I helped! ☺
Is the answer you are looking for Gravity? Gravity is what pulls us down to earth.
Explanation:
It is given that,
Speed, v₁ = 7.7 m/s
We need to find the velocity after it has risen 1 meter above the lowest point. Let it is given by v₂. Using the conservation of energy as :




So, the velocity after it has risen 1 meter above the lowest point is 6.26 m/s. Hence, this is the required solution.
<span>Examples of outside forces acting on a car is gravity, wind, and other cars. Cars do not slide down hills because their weight, combined with the friction of their tires against the road, hold them in place. </span>
Answer:
yes i agree
Explanation:
because law of inertia state that object remain at rest or in motion unless external force apply on it
