Given, that the angle of the stone is θ = 60∘. Solve this by using the trajectory formula? Find the equation of the path of the projectile. Question 2: If the initial velocity of a stone thrown by a boy is 6 m/sec, and the angle at which the stone is thrown is 60∘. Subsituting it in the formula y = h + x * (V₀ * sin(α)) / (V₀ * cos(α)) - g * (x / V₀ * cos(α))² / 2 we get, Time is taken by the ball in the air = 4 sec The initial velocity of the ball is hence 6m/sec Given that the angle of the ball with the ground is 60 degrees. Calculate the vertical distance covered by the ball in the meantime. To find vertical velocity in projectile motion of particle, when the initial velocity changes, using the calculator, follow the steps: Step 1: Mention the values of initial velocity, acceleration due to gravity (9. If it moves at the rate of 6m/s and John catches it after 4s. In other cases we may choose a different set of axes.Question 1: Jack throws a ball at an angle of 60 degrees in the air. Answer: Projectile and projectile motion: When an object is launched into the air, it travels along a curved path under constant acceleration that is directed toward the centre of the Earth. It is not required that we use this choice of axes it is simply convenient in the case of gravitational acceleration. Question 1: Define projectile, projectile motion, and trajectory and write the equation of horizontal and vertical displacement in projectile motion. (This choice of axes is the most sensible because acceleration resulting from gravity is vertical thus, there is no acceleration along the horizontal axis when air resistance is negligible.) As is customary, we call the horizontal axis the x-axis and the vertical axis the y-axis. The key to analyzing two-dimensional projectile motion is to break it into two motions: one along the horizontal axis and the other along the vertical. We discussed this fact in Displacement and Velocity Vectors, where we saw that vertical and horizontal motions are independent. The most important fact to remember here is that motions along perpendicular axes are independent and thus can be analyzed separately. Calculate the trajectory of a projectile. In this section, we consider two-dimensional projectile motion, and our treatment neglects the effects of air resistance. Find the time of flight and impact velocity of a projectile that lands at a different height from that of launch. The motion of falling objects as discussed in Motion Along a Straight Line is a simple one-dimensional type of projectile motion in which there is no horizontal movement. Such objects are called projectiles and their path is called a trajectory. The horizontal range, R, of a projectile launched from the same initial and final vertical displacement can be calculated as R 2 v ( ) ( ) g, s. Some examples include meteors as they enter Earth’s atmosphere, fireworks, and the motion of any ball in sports. The applications of projectile motion in physics and engineering are numerous. (b) We can find the final horizontal and vertical velocities v x v x and v y v y with the use of the result from (a). Thus, any projectile that has an initial vertical velocity of 21.2 m/s and lands 10.0 m above its starting altitude spends 3.79 s in the air. Projectile motion is the motion of an object thrown or projected into the air, subject only to acceleration as a result of gravity. The time for projectile motion is determined completely by the vertical motion.
