A car travels with a velocity of 20ms for 6 second it then


A car travels with a velocity of 20m/s for 6 second. It then uniformly brought to rest in 4 seconds. Draw a velocity against The sun radiates energy at a rate of 4 x 10^26 joules/second. Calculate the lifetime of the sun if it began shining with 8 x 10^36 joules of rotational energy. On the basis of your calculations, does this explanation for the sun's energy production seem reasonable? Explain. time graph
