The gravitational force exerted on a baseball is 2.24 N down. A pitcher throws the ball horizontally with velocity 17.0 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 183 ms. The ball starts from rest. Through what distance does it move before its release? What are the magnitude and direction of the force the pitcher exerts on the ball?

Answers

To have a weight of 2.21N., the ball's mass is (2.21/9.8) = .226kg. 
a) d = 1/2 (vt), = 1/2 (18 x .17), = 1.53m. 
b) Acceleration of the ball = (v/t), = 18/.17, = 105.88m/sec^2. 
f = (ma), = .226 x 105.88, = 23.92N.

Okay so I'm struggling at this particular set of questions on Khan Academy. Anyone got any ideas?

Answers

my best guess is 135 because if it can fit cubes with 1/4 inch sides, that means it can fit 9 cubes going lengthwise, and 3 cubes wide which is 27 cubes on the base. then it can fit 5 cubes, all 1/4 inch going up because in 1 1/4 inch there are 5 quarter inches. so if you multiply 27 by 5 you get 135. I hope that helps a little bit:)

I know this is not much help but I wrote all my work down and got 135 as well so I’m glad you got the correct answer. You will struggle sometimes, especially with challenging questions like that but remember it will always get easier as you go alone((: good luck to you!
