Scotslad Posted August 23, 2015 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.
John Cuthber Posted August 23, 2015 Posted August 23, 2015 potential/kinetic energy equations. It looks like they covered what you need.
Prometheus Posted August 23, 2015 Posted August 23, 2015 Tell us what you've done and in particular where you are stuck.
studiot Posted August 23, 2015 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.
Scotslad Posted August 23, 2015 Author 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
studiot Posted August 23, 2015 Posted August 23, 2015 Yes well done +1 Come back if you still need help.
