At what launch angle or angles will the projectile land at half of its maximum possible range?
The half maximum range of a projectile is launched at an angle of 15 degree
What is the correct angle of throwing a javelin?
The correct angle of throwing a javelin is 45 degree.The physics concept behind this is known as impulse.According to this law if an object is thrown at an angle of 45 degree it travels much range(horizontal distance) than throwing at any other angle this law not only applies for javelin but also for firing an cannon or shooting a gun on an arrow into the space.
What type of angle is 20 degree?
A 20-degree angle is classified as an acute angle. Acute angles are those that measure less than 90 degrees. Therefore, since 20 degrees falls within that range, it is indeed considered acute.
How do you find the maximum range and height for angles 30 45 and 60?
1. You need to know the velocity of the projectile (V0) 2. The expressions for the range and height assume no air resistance (in vacuum) 3. The units must be consistent e.g. metres and g = 9.81 m/s2 Range in metres for 30 degree launch angle = sin 60 x V02 / 9.81 Range in metres for 45 degree launch angle = sin 90 x V02 / 9.81 Range in metres for 60 degree launch angle = sin 120 x V02 / 9.81 Max. height in metres for 30 degree launch angle = (V0 x sin 30)2 / 2g Max. height in metres for 45 degree launch angle = (V0 x sin 45)2 / 2g Max. height in metres for 60 degree launch angle = (V0 x sin 60)2 / 2g 2g is of course 9.81 x 2 = 19.62 m/s2 For interest, at 45 degree launch angle the max. height is 25% of the range.
What is 147 degree angle called?
A 147-degree angle is classified as an obtuse angle. Obtuse angles are defined as angles that measure greater than 90 degrees but less than 180 degrees. Therefore, since 147 degrees falls within this range, it is specifically an obtuse angle.
What angle for firing projectiles gives the longest range?
It depends on the weapon. A rifle will have a very low angle--maybe ten degrees. A mortar needs a very high angle to give a good range. And a howitzer needs about a 45 degree angle to give long range.
Why javelin is thrown at 45 degree angle?
The javelin is ideally thrown at a 45-degree angle to maximize its horizontal distance. This angle allows for an optimal balance between vertical lift and horizontal distance, utilizing the forces of gravity and aerodynamic lift effectively. While the actual optimal angle can vary based on factors like speed and technique, 45 degrees serves as a theoretical benchmark for achieving maximum range in projectile motion.
What are the characteristics of projectiles?
Projectiles are objects that are thrown, launched, or propelled into the air and are primarily influenced by gravity and air resistance. They typically follow a curved trajectory known as a parabolic path, which is determined by the initial velocity, angle of launch, and acceleration due to gravity. Key characteristics include their range, maximum height, and time of flight, which can be calculated using kinematic equations. Additionally, projectiles do not have propulsion after launch, relying solely on their initial velocity and gravitational pull.
Is a obtuse angle 110 degree?
No, but 110 degrees is an obtuse angle. An obtuse angle can be anything in the range (90, 180) degrees.
At what launch angle or angles will the projectile land at half of its maximum possible range?
The half maximum range of a projectile is launched at an angle of 15 degree

Is 200 degree an obtuse angle?
No. An obtuse angle has a measure in the range (90, 180) degrees. The angle in question is greater than the maximum value for an obtuse angle.
Water is projected from two rubber pipes at the same speed-from one at an angle of 30 and from the other at 60why are the ranges equal?
w2hen the angle of projection is larger than 45 degree the height attained will be more but the range is again less.in this case angle is 30 degree which is less than 45 degree and 60 degree angle is greater than angle of 45 degree which have less range and is equal to range of 30 degree .so ranges are equal.
What type of angle is a 168 degree angle?
A 168-degree angle is classified as a reflex angle. A reflex angle measures greater than 180 degrees but less than 360 degrees. In this case, 168 degrees falls within the range of a reflex angle because it is greater than 180 degrees.
What type of angle is 20 degree?
A 20-degree angle is classified as an acute angle. Acute angles are those that measure less than 90 degrees. Therefore, since 20 degrees falls within that range, it is indeed considered acute.

Why does a catapult shoot best from a 45 degree angle?
The [horizontal] range of a projectile is maximised when it shoots at a 45 degree angle. This is true if air resistance is ignored so that the only force acting on the projectile is gravity.
