1.2: A skydiver jumps from an airplane at an altitude of 500 meters. If the skydiver experiences a freefall for 5 seconds before opening the parachute, what is the skydiver’s velocity and altitude at that moment? Here, we provide detailed answers to the exercises

Solution: The velocity equation is: $ $v(t) = v_0 - gt$  $v(2) = 20 - 9.8 ot 2 = 0.4 ext{ m/s}$ $ The acceleration is constant and equal to -g: $ $a(t) = -9.8 ext{ m/s}^2$ $ 4.1: Derive the differential equation for freefall motion. The answers provided here serve as a starting

Solution: Using the same kinematic equations: $ $v(5) = 0 + 9.8 ot 5 = 49 ext{ m/s}$  $y(5) = 500 + 0 ot 5 - rac{1}{2} ot 9.8 ot 5^2 = 500 - 122.5 = 377.5 ext{ m}$ $ 2.1: Plot the altitude-time graph for an object dropped from an altitude of 200 meters.

Solution: The altitude-time equation is: $ $y(t) = 200 - rac{1}{2} ot 9.8 ot t^2$ $ By plotting this equation, we obtain a parabola that opens downward, indicating a decrease in altitude over time. 3.1: An object is thrown upward from the ground with an initial velocity of 20 m/s. Calculate its velocity and acceleration at t = 2 seconds.

The altitude of an object in freefall is a critical parameter that determines its position and velocity at any given time. By applying mathematical models, such as kinematic equations and differential equations, we can accurately predict the altitude, velocity, and acceleration of an object in freefall.
