What is the angle between acceleration and velocity at the highest point?
90∘
What is the angle between the velocity and acceleration vectors at these times?
It depends on the system which you are working on. If the motion is circular then the angle between velocity vector and acceleration is 90°.
At what point of projectile angle between velocity and acceleration is acute?
At the highest point of a projectile, the vertical component of velocity is zero and the velocity is entirely horizontal. The direction of acceleration (due to gravity) is vertically downwards throughout the motion of the projectile.
At what point in the oblique projectile motion angle between velocity and acceleration is 90 degree?
Horizontal range It is defined as the maximum distance covered in horizontal distance. 3 ) Define trajectory. At highest point, the velocity of the body is u cos θ in horizontal direction and the angle between the velocity and acceleration is 90°.
What will happen to the range if you double the velocity?
Substituting the time taken for the projectile to hit the ground again into the displacement function in the horizontal direction, , we can get the function for the range of projectile. Therefore, doubling the initial velocity will result in the range being 4 times the original.
What effect does doubling the initial velocity have on the range?
Doubling the initial speed will make the range 4x larger as in the formula dx=vxtthe initial velocity, it doubles both the velocity and the time.
How would the horizontal range change if the initial velocity is doubled?
So, if initial velocity is doubled then horizontal range will be quadruple.
How does range depend on initial velocity?
The horizontal displacement of the projectile is called the range of the projectile and depends on the initial velocity of the object. If an object is projected at the same initial speed, but two complementary angles of projection, the range of the projectile will be the same.
Is the time of flight of a projectile is doubled what happens to the maximum height attained?
Time of flight is the time taken by body to reach the projection. Thus, we know that H is directly proportional to the square of the time of flight. If time of flight doubles then the maximum height will increase by 4 times. Hence, the correct answer is option (D).
When the initial velocity of a projectile is doubled what will happen to its horizontal range and maximum height?
What will be the effect on horixontal range of a projectile when its initial velocity is doubled, keeping the angle projection same ? It means if (u) is bounled, the horizontal range becomes four times the original horizontal range.
What happens to the height of tsunami when the velocity is doubled?
The radius of the circular path is directly proportional to the depth of the water. Thus, the speed of a water wave is proportional to its amplitude. The takeaway message is that the height of a tsunami doubles if its speed is doubled.
What happens to time of flight when initial velocity is doubled?
You should change “Velocity” to “Speed.” If you double the speed, the time of arrival of your plane will be sooner. For example: Instead of 6 hours flight, your plane will arrive in 3 hours, if your plane doubled the speed to fly.
