YAY! from that, I got it. Thank you! :)

but isn't Q already 6000J/h? i am looking for temperature which is T.. so should i rearrange fore T= Q/mc ? Q= heat or energy absorbed (J) = 6000J/h m= mass (kg) = 0.965kg c= specific heat capacity(J/(kg°C) ) = for copper: 3.8 x 10^2 and for glass: 8.4 x 10^2 right?

1000J in 10 minutes 60/10 = 6 ∴ 6 x 1000 = 6000J in one hour?

Homework Statement Two pitchers of lemonade are left sitting in the sun at a picnic. One pitcher is made of copper and the other of glass. If each empty pitcher has a mass of 965 g and absorbs 1.0 x 10^3 J of energy 10.0 minutes, calculate the temperature increase of both empty pitchers in...

i'm still not sure how to do this.. :( could you please look just above this, which are the reasons why i do not understand this

okay so using the first equation for part a) I would have to rearrange it in order to find v2? meaning... v1 = 0 m/s (which makes sense) Δt= 12s or 5s (12s, which is the time for the acceleration or 5s, which is the time for the constant velocity) Δd= .. i am not even sure and i DID mean the...

Homework Statement An object starts at rest and accelerates at 2.5 m/s^2 for 12 seconds. It then moves at a constant velocity for 5.0 seconds and then slows down uniformly at 1.5 m/s^2 until it stops. Calculate: a) the constant velocity b) the time taken for deceleration c) the total...
