1.2: What is the SI unit of force?
\[s = 0 + rac{1}{2}(4)(5)^2 = 50 ext{ m}\] --- University Physics Harris Benson 3rd Edition Answer
5.2: A 2-kg block is lifted vertically upwards by 5 m. If the acceleration due to gravity is 9.8 m/s^2, what is the gain in potential energy? m is the mass
University Physics Harris Benson 3rd Edition Answers: A Comprehensive Guide** and h is the height.
6.1: What is the law of conservation of momentum?
\[ ext{Vector: displacement, velocity, acceleration} \]
Using the equation: $ \(U = mgh\) $ where U is the potential energy, m is the mass, g is the acceleration due to gravity, and h is the height.
