Question

No mass given, can you give me the answer to 3 and 4 also pls

1. A solid sphere rolls from a height of 8 meters down a frictionless track propped at 35 degrees from the table. What is its kinetic energy at the bottom of the track? (assume no lost of energy due to friction). no mass given

2. If the ball then rolls off the table (2 meter high) and lands on the ground, with a horizontal speed of 16m/s2,what would be the

a) horizontal speed when it lands?

b) vertical speed when it lands?

c) the total velocity when it lands?

3. What would happen to the acceleration if the angle of the track was raised to 60 degrees?

4. What would happen to the acceleration if the mass of the ball was doubled ?

Answer 1

3 for an objectsding down a lope a aoc Cacceler aonue ushich ac ouonwards ivide Ccc into au and a Sínce is alang the no aceelerahion ofobject fs is constant. → accelerahonge Increased Acceleratisof a body is ndeb endent of of objectt. be, So, c o bject t. e, So, No cha n accaleraha acalra

Also , here since acceleration is g.sin(theta) and doesn't depends on mass . So acceleration does not change with change in mass.

If you still have any confusion then please let me know in the comments section.

Thank you.
