What is the kinetic energy of the ball at the highest point of its motion?
At its highest point the vertical motion is 0.0 m/s. Its horizontal motion is: (20 m/s) * cos 40. Its Kinetic energy is 0.5 *0.200 kg * (20m/s * cos 40)^2.
What is the kinetic energy of the ball when it reaches the maximum height of its parabolic arc?
Kinetic energy equals half mass times velocity squared (1/2mv^2) and so if the projectile is traveling on a parabolic path it depends on the mass and velocity. However if it is traveling directly upward, at its highest point the velocity would equal zero, and so the kinetic energy would also be zero.
Which ball possesses the greatest amount of kinetic energy?
First, heavier objects that are moving have more kinetic energy than lighter ones: a bowling ball traveling 10 m/s (a very fast sprint) carries a lot more kinetic energy than a golf ball traveling at the same speed.
What is the kinetic energy of the ball as it is half way through the fall?
The kinetic energy of the ball 1/2 way through the fall will be equal to 2kg9. 820 meters or 392 Joules, because the kinetic energy and potential energy are the same at this point.
What is the kinetic energy of the ball at the highest point?
The initial kinetic energy, E=(1/2 )mv^2. the horizontal velocity: v×cos45°=v/√2. When the ball reaches the highest point, it’s vertical velocity becomes zero and it’s horizontal velocity remains the same. Thus, it’s velocity at the highest point is equal to its horizontal velocity.
What happens to kinetic energy at 45 degrees?
At 45 degrees initial horizontal and vertical velocities (so momenta) are equal while at the highest point the vertical component drops to zero which means kinetic energy has dropped to 1/2 of its initial value as the second half was transfered into potential energy.
What is the velocity of a 200g ball thrown by a boy?
A boy throws a ball of mass 200g with a velocity 20m/s at an angle of 40° with the horizontal. Originally Answered: A boy throws a ball with a mass of 200g with a velocity 20 m/s at an angle 40° with the horizontal.
What is the horizontal velocity of the ball at the highest point?
the horizontal velocity: When the ball reaches the highest point, it’s vertical velocity becomes zero and it’s horizontal velocity remains the same. Thus, it’s velocity at the highest point is equal to its horizontal velocity.
