Acceleration of a rock at the top of its trajectory when thrown straight upward?
Any object moving under the influence of gravity only and no other outside forces has a constant acceleration of 9.8 meters (32.2 feet) per second2, directed down.The speed changes. The acceleration doesn't, regardless of the angle, speed, trajectory, color, temperature, cost, size, mass, or weight of the falling object.
What is the acceleration of a stone at the top of its trajectory when it has been thrown straight upward?
At the top of its trajectory, the acceleration of the stone is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 directed downward. This is because at the highest point, the stone momentarily comes to a stop before it starts falling back down.
Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?
The speed of the ball is greatest when it is thrown upward and decreases as it reaches the peak of its trajectory. The speed continues to decrease as the ball falls back down due to the force of gravity pulling it towards the ground.
How long does it take for an object thrown straight upward with a velocity of 50 m second to reach the peak of its path?
To find the time taken for an object to reach the peak of its path when thrown straight upward with a velocity of 50 m/s, you can use the formula: time = velocity / acceleration. Since the object is moving against gravity, the acceleration will be the acceleration due to gravity (-9.81 m/s^2). Therefore, the time taken to reach the peak will be 50 m/s / 9.81 m/s^2 = approximately 5.1 seconds.
How will the speed of a ball thrown upward and a ball thrown downward compare upon striking the ground?
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.
Acceleration of a rock thrown straight upward at the moment it reaches the tippy-top of its trajectory?
9.8 m/s (2) Squared

An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
12) What is the definition of trajectory?
The curve which a body describes in space, as a planet or comet in its orbit, or stone thrown upward obliquely in the air.
What is tje meaning of trajectory?
The curve which a body describes in space, as a planet or comet in its orbit, or stone thrown upward obliquely in the air.

A cricket ball is projected vertically upward what kind of acceleration is acting on the ball?
When a cricket ball is projected vertically upward, the acceleration acting on the ball is gravitational acceleration directed downward. This causes the ball to slow down until it reaches the highest point of its trajectory, then it accelerates back downward due to gravity.
When will objects thrown upward start to go down?
When the vertical component of their velocity has dwindled to zero because of the acceleration of gravity.
If a rock is thrown upward what must be its acceleration at the top of its flight?
At the top of its flight, the acceleration of the rock must be equal to the acceleration due to gravity acting downward. This acceleration is approximately 9.8 m/s^2 on Earth.
