What is the initial velocity of a ball thrown vertically upwards?
When it is thrown vertically upward, it gains an initial velocity and acceleration. Sep 17, 2015 · I chose A because since the acceleration of the ball is positive vertically upwards, the acceleration downwards is negative, and at the turning point, acceleration is zero. The initial velocity of the ball is = 20 m/s.
At what speed a ball must be projected vertically upward?
The Questions and Answers of At what speed a ball must be projected vertically upward so that distance travelled by it in 5thsecond is equal to distance travelled in sixth second (in m/s):-Correct answer is ’49’.
When a ball is thrown upward its initial velocity is?
The velocity with which the ball is thrown upward is \[{V_0}\] and it can be termed as the initial velocity of the ball. The drag force which affects the motion of the ball is represented as \[m\gamma {v^2}\] . We are asked to find the time taken by the ball to rise to the highest position.
When a ball reaches maximum height What is the acceleration?
Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is: Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero….Objects Launched Upward.
| Variable | Value |
|---|---|
| a | -9.8 m/s2 |
| t | 0.40 s |
When a ball is thrown up vertically with velocity v0?
When a ball is thrown up vertically with velocity vo it reaches a maximum height of h. If one wishes to triple the maximum height then the ball should be thrown with velocity.
When a body is thrown up vertically with initial velocity u?
A body is thrown vertically upwards with an initial velocity u reaches the maximum height in 6s. The ratio of the distance traveled by the body in first second to seventh second is. Since the paticle reaches maximum height in 6 s, at 7th second travel, its initial velocity is zero.
What will be the velocity of a ball thrown vertically upwards when it reaches the maximum height?
Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is: Answer: 0 m/s…….What will be the velocity of a ball thrown vertically upwards when it reaches the maximum height?
| Variable | Value |
|---|---|
| a | -9.8 m/s2 |
| t | 0.40 s |
How is a Ball projected with a certain initial speed?
A ball is projected vertically upwards with a certain initial speed. Another ball of the same mass is projected at an angle of 60° with the vertical with the same initial speed. At the highest point, the ratio of their potential energies will be A 4:1 B 32 © 23 D 21 > A ball is projected vertica…
How to calculate the velocity of a ball thrown upward?
A ball is thrown vertically upward with a velocity of 20 m/s. calculate maximum height and time taken to reach maximum height. H = U2/ (2g) = (202)/ (2 x 9.8)=20.4 m T = U/g = 20/9.8 = 2.04 sec A ball is thrown vertically upwards. it returns 6s later.
How to calculate the height of a vertically thrown object?
So (from equation ii and vi) for a vertically thrown object the total time taken for its upward and downward movements = t + T=2v1/g ………. (vii) 1) The maximum height reached by it would be = v12/2g= (98 x98 )/ (2 x 9.8) meter = 490 meter.
Why does an object thrown upwards come down after reaching a point?
Why an object thrown upwards comes down after reaching a point? When an object is thrown with certain initial velocity (say V), it gains a Kinetic energy at that moment of throwing. As it moves upwards from its initial position (wherefrom it’s thrown) and gains height, its potential energy rises.
