xcvxcvvc said:.5 * 9.8 * t^2 = 409.5
t = squareroot(409.5/(.5*9.8))
9.8 * t = answer for b and t is the answer for a
The time of impact in a body fall can be calculated using the formula t = √(2h/g), where t is the time, h is the height of the fall, and g is the acceleration due to gravity (9.8 m/s²).
The velocity at impact in a body fall is affected by the height of the fall, the mass and shape of the falling object, and air resistance. Other factors such as the surface material and angle of impact may also play a role.
Air resistance, also known as drag, can significantly affect the kinematics of a body fall. As the falling object accelerates, the force of air resistance increases, eventually reaching a point where it balances the force of gravity and the object falls at a constant speed (known as terminal velocity). This can impact the time and velocity at impact.
The time and velocity at impact in a body fall are inversely related. This means that as the time of impact increases, the velocity decreases, and vice versa. This relationship can be seen in the formula v = gt, where v is the velocity, g is the acceleration due to gravity, and t is the time.
The kinematics of a body fall can be applied in various real-world scenarios, such as analyzing the impact of a fall on the human body, designing safety equipment for extreme sports, and understanding the mechanics of meteorite impacts. It can also be used to calculate the trajectory and impact of falling objects, such as in engineering and construction projects.
