The height in feet of a projectile launched vertically from the ground with an initial velocity $v_{0}$ in feet per second is given by the formula $h=-16 t 2+v 0 t,$ where $t$ represents time in seconds. For each problem, calculate the height of the projectile given the following initial velocity and times. $v=64$ feet/second, at times $t=0,1,2,3,4$ seconds

Key Concepts

Kinematic Equations

Kinematic equations are the formulas used in mechanics to describe the motion of objects. They relate variables such as displacement, velocity, acceleration, and time, and are fundamental in modeling and solving problems involving projectile motion.

Initial Velocity

Initial velocity is the speed at which a projectile is launched in a given direction. It is a critical parameter in calculating the trajectory and maximum height of the projectile by determining the initial kinetic energy and subsequent motion.

Gravitational Acceleration

Gravitational acceleration is the constant acceleration imparted to objects due to the force of gravity. In projectile motion, this acceleration is incorporated into the height equation, where it usually appears as a term that multiplies the square of time, reflecting the influence of gravity on the projectile's motion.

Quadratic Functions

Quadratic functions are polynomial functions of the form ax² + bx + c. They are used to model the vertical displacement of a projectile over time, where the quadratic term represents the effect of constant acceleration due to gravity.

Projectile Motion

Projectile motion refers to the motion of an object that is launched into the air and is subject only to the acceleration of gravity. This type of motion is characterized by a parabolic trajectory and involves factors such as initial velocity, time, and gravitational acceleration.
