acceleration at its Highest point? (C) How long does it take for the Bullet to hit the ground?
Did you know that when a bullet is fired from a gun, it follows a parabolic trajectory due to its initial velocity? In this case, the bullet has a horizontal component of 100 m/s and a vertical component of 200 m/s. Let's find out some interesting facts about the bullet's motion.
A) To reach its highest point, the bullet will take some time. This can be calculated by considering the vertical motion of the bullet. By using the formula of motion, we can determine that the time taken by the bullet to reach its highest point is approximately 2 seconds.
B) At its highest point, the bullet's velocity and acceleration have interesting properties. The velocity at this point is purely horizontal, as the vertical component of the velocity becomes zero. Thus, the velocity at the highest point is 100 m/s, solely in the horizontal direction. However, the acceleration at the highest point is solely vertical, due to the effect of gravity. The bullet experiences an acceleration of approximately -9.8 m/s^2, acting downward.
C) Finally, let's explore the time it takes for the bullet to hit the ground. Using the formula of motion, considering the vertical displacement and acceleration due to gravity, we can determine that the bullet will take approximately 4 seconds to hit the ground.
In conclusion, when a bullet is fired from a gun, it follows a parabolic trajectory. It takes 2 seconds to reach its highest point, where its velocity becomes purely horizontal at 100 m/s, while experiencing a vertical acceleration of approximately -9.8 m/s^2. The time it takes to hit the ground is approximately 4 seconds.
