I was thinking of doing that but I wasn't confident whether I could cancel but I'm now regretting my lack of confidence. Thanks.

T(t) = T[e] + e^-rt (T(0) - T[e]) Where r = -0.001 At T(120) = 86.632 => 86.632 = T[e] + e^-(-0.001*120) (T[0] - T[e]) 86.632 = T[e] + T[0] e^0.12 - T[e]e^0.12 This is why I don't understand what to do because I have no idea how I should even be substituting, or what I should be substituting...

*Given Newton's Cooling formula, where T(t) predicts temperature, and where Te is the temperature of the enviornment, T[0] is the temperature when t = 0: T(t) = Te + (T[0]+Te)e^-rt predict Te when T(120)= 86.632 T(240) = 79.210 r = 0.001 I don't know how to even remotely go about solving...

Homework Statement A particle moves in the x-y plane relative to a fixed point O. Initially, the particle is at the point 6i-2j, where I and J are position vectors in the directions of the x and y-axis respectively. The particle moves such that t seconds after the start of its moition, the...

I'm very new to physics and am doing a crash higher course. I am currently tackling dynamics, and here is one of the questions I was given. 8 ) A car of mass 800kg is accelerated from rest to 18m/s in 12 seconds. a) What is the size of the resultant force acting on the car b) How far does it...
