Scotslad Posted August 23, 2015 Share Posted August 23, 2015 I have a question which involves working out the final speed of a falling object when it hits the deck. All I am given in the question is the height, the acceleration due to gravity and obviously the initial speed, i.e. 0 m/s The context of the question is in relation to rearranging equations and substitution. The block has covered basic velocity, acceleration, momentum and potential/kinetic energy equations. Any guidance gratefully appreciated. Link to comment Share on other sites More sharing options...
John Cuthber Posted August 23, 2015 Share Posted August 23, 2015 potential/kinetic energy equations. It looks like they covered what you need. Link to comment Share on other sites More sharing options...

studiot Posted August 23, 2015 Share Posted August 23, 2015 I have a question which involves working out the final speed of a falling object when it hits the deck. So post both the actual question and your attempt so far. Don't worry if it is not right, that is the way we learn. Link to comment Share on other sites More sharing options...
Scotslad Posted August 23, 2015 Author Share Posted August 23, 2015 I think I have it now If mgh = 1/2mv2 then I think the mass is not required to work out the final speed and therefore I could rearrange to make v the subject.....I think 3 Link to comment Share on other sites More sharing options...
studiot Posted August 23, 2015 Share Posted August 23, 2015 Yes well done +1 Come back if you still need help. Link to comment Share on other sites More sharing options...
