What else can I help you with?
Can you cite an example in which the acceleration of a boby is opposite in direction to it's velocity?
When an object is thrown upward, the acceleration due to gravity acts downward while the velocity is directed upward. This leads to a decrease in the speed of the object until it reaches its highest point and changes direction.
Which car in the table has the highest acceleration capability?
The car with the highest acceleration capability in the table is the one with the fastest acceleration time.
When is an athletes highest acceleration in a race?
An athlete's highest acceleration in a race typically occurs during the initial phase after the start, as they push off the blocks or starting line. This period, often referred to as the acceleration phase, lasts for about the first 10 to 30 meters, depending on the race distance and the athlete's speed. After reaching peak acceleration, the athlete transitions into maintaining their maximum velocity, which can vary based on the individual's sprinting technique and conditioning.
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
A person on a very high cliff throws a ball vertically up at an initial speed of 13.0 ms Neglect friction whats the speed at the highest point the acceleration at the highest point?
At the highest point, the speed of the ball is 0 m/s because it momentarily stops before falling back down. The acceleration at the highest point is equal to the acceleration due to gravity (approximately -9.8 m/s^2) acting in the downward direction.
Where is the speed of a simple harmonic oscillator equals to zero?
At the highest and lowest extremes of its travel, at the points where it changes its direction of motion.
Is it true to say that a projectile has zero acceleration at its peak. If yes explain if not give a reason?
Yes, it is true to say that a projectile has zero acceleration at its peak.Because the highest height, which the object will reach is known as the peak of the object's motion. The increase of the height will last, until vy = 0.,For more Explanation:Atlas_gondal@yahoo.com
Can an object have a speed of zero and the acceleration not be zero?
Yes, but only at one instant. For instance, if you throw an object straight up, when it reaches the highest point its instantaneous speed is zero, but of course its speed is changing - thus, acceleration is non-zero.
Can a body have acceleration with zero velocity?
Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
When is fuel consumption at its highest?
it is at its higher at acceleration
When is acceleration neg?
Acceleration is negative if velocity is decreasing with time. Since velocity is a vector this can occur in one of two ways: 1) you are slowing down in the direction of motion and the velocity in that direction is defined as positive (this is what we usually mean by negative acceleration) 2) you are speeding up in the direction of motion and the velocity in that direction is defined as negative. An example of this is an object launched into the air which immediately starts to decelerate in it's upward velocity, reaches it's highest velocity, and then begins accelerating towards the ground. If we call the velocity upward a positive velocity, then when it starts falling, it has negative velocity. Note that acceleration (due to gravity) is negative the whole time.
What is the acceleration of a 4kg ball tossed vertically upward when the ball is at its highest point?
No matter what the mass of the ball is, or what direction you toss it, it has the same acceleration from the moment it leaves your hand until it hits the ground ... the acceleration due to gravity, on Earth or wherever you're playing the game, pointing down. On Earth, it's 9.8 meters (32.2 feet) per second2.
