Answer:

107 kJ

Explanation:

12.00 kg * 913 J /kg-C * (118-20)°C        ( I corrected spec heat units)

                    ( a  C degree change is the same as a kelvin change)

                   = 1 073 688 J   = 107 kJ   ( three sig digits)

kobusy [5.1K]

Answer:

Explanation:

a = 4ms⁻²,  Vf = 180 m/s  &  Vi = 140m/s

a = \frac{Vf-Vi}{t}

4 = \frac{180-140}{t}

t = 40/4

t = 10sec

To Measure Distance Use third Equation of Motion:

2aS = Vf²-Vi²

S = \frac{180*180 - 140*140}{2(4)}

S = 12800/8 = 1600m
