Hi, I recently stumbled across your forums whilst trying to find help for my homework. I have managed to do all the questions on the homework except these 2, and i cannot seem to get the right answers to them. This is because they both miss one piece of data and i would normally use the suvat equations to find the answer.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A body moving with uniform acceleration covers 64.4m in 7 seconds. And 110m in 10 seconds.

Find acceleration and initial velocity.

2. Relevant equations

Suvat / equations of motion

3. The attempt at a solution

(110 - 64.4 ) / (10- 3)

The only other thing i could think of would be adding them and trying to work it out.. but as i dont know the start velocity i cant. ( 174.4 / 17)

Question 2

1. The problem statement, all variables and given/known data

A body released from rest falls through 44.1m during the fifth second of its motion find the acceleration due to gravity.

u= 0, s(5) - s (4) = 44.1m

Sorry theres not much working out from me, Im just new to physics (started it about a month ago) and asides from filling in data into the suvat equations i really have no idea what im doing. could somebody point me in the right direction , thankyou
