Doc Al said:The time given is the total time in the air. So what's the time it took to reach the highest point?
Yes, the numbers are comically unrealistic. Worth checking that you copied the problem correctly, but it's also not unusual for problems to use unrealistic data. (Unfortunately.)Filip Larsen said:Based on the numbers you quote the result is correct, but then it sure is one fast truck. If I were you I would double check that the given numbers are correctly taken from the problem text.

Simple kinematics is the study of the motion of objects without considering the forces that cause the motion. It involves analyzing the position, velocity, and acceleration of an object as it moves in a straight line or along a curved path.
The basic equations used in simple kinematics are the equations of motion, which include:
- Position equation: x = x0 + v0t + 1/2at2
- Velocity equation: v = v0 + at
- Acceleration equation: a = (v - v0) / t
- Time equation: t = (v - v0) / a
Where x is the position, x0 is the initial position, v is the velocity, v0 is the initial velocity, a is the acceleration, and t is the time.
Simple kinematics focuses on the motion of objects along a straight line or curved path, while other branches of kinematics may involve studying the motion of objects in more complex situations, such as circular motion or motion in a 3D space.
Simple kinematics can be applied to various real-life situations, such as calculating the distance traveled by a car, determining the speed of a moving object, or predicting the trajectory of a projectile. It is also used in fields such as engineering, robotics, and sports to analyze and improve the motion of objects.
To solve problems using simple kinematics, you need to identify the given quantities, such as initial and final positions, velocities, accelerations, and time. Then, you can use the appropriate equation(s) to calculate the unknown quantity. It is important to pay attention to units and use consistent units throughout the calculations.
