An increase in angular acceleration will decrease linear acceleration if the radius is held constant. (True / False)

If all other factors are held constant, what effect would "choking up" ( moving the hands away from the "handle of the bat") on a bat have on the resultant linear velocity of a hit ball? If the angular velocity of a batter's shoulders increases, what will happen to the linear velocity of...

when angular velocity is 0, is it true that angular acceleration must also be zero?

Can someone please point me in the right direction to find the answer to this problem. I have searched and searched. Which of the following statements is true about the relationship between impact and impulse? A. impact is always greater than impulse B. impulse is always greater than...

Does Newton's law of gravitation exist outside the Earth's atmosphere?

thanks. next one A ball is kicked with an initial velocity of 10 m/s at an angle of 30 degrees. Neglecting air resistance, what is the speed of the ball at landing? Answer: 10 m/s, the ball will slow down on the way up and speed back up on the way down, maxing out at the initial velocity

when it says the components of vector mechanics, are they just talking about the x and y components? Or the horizontal and vertical compponents?

thanks I am new to this stuff and I am trying to figure it out. got time to help on more?

1st question: I am thinking that acceleration is positive 2nd question: initial vertical velocity and relative projection height 3rd question: the vertical components, but not sure if their are specific vertical components

questions I need help with When final velocity is larger than initial velocity, then acceleration is what? What affects the time that a horizontally projected object remains in the air? What components of projectile are affected by gravity?

can someone help me with some basic questions

can anyone in here help me with some questions

is anyone online?

hey I am new here and need some help with a few basic questions
