Ball and a spring#

I have built a game that involves a spring, a smooth slope, and a little ball of \(m = \)0.30000000000000004 kg. The slope is 29\(^{\circ}\) above the horizontal. The spring is placed into a small hole such that when it is compressed to the proper starting position, and the ball is placed upon it, the ball will be at the height \(h = \)0 m. The spring has been compressed by 3 cm and has a spring constant of \(k = \)900 N/m.

Part 1#

When I press a button, the ball is pushed up the slope by the spring. How fast is the ball traveling when it is m up the slope?

Part 3#

What is the maximum DISTANCE the ball reaches from the bottom of the slope?

Answer Section#

Please enter in a numeric value in \( m{m}\).

Part 4#

Calculate the acceleration of the ball as it goes UP the slope once it is beyond the spring?

You may draw a free body diagram in order to help you write the final acceleration vector in terms of \(\hat\imath\) (pointing down-slope) and \(\hat\jmath\) (pointing perpendicular to the slope). Enter answer as a symbolic expression (sin(30) instead of 0.86602).
