A man decided to ride his car at 10 kph for the first 5 seconds. He then accelerates at 1 m/s for the next 5 seconds, 2 m/s for the next 5 seconds, 3 m/s2 for the next 5 seconds, and so on and so forth. (a) At what time will he reach a velocity of 60 kph? (b) What is the total distance (m) traveled after he has reached a velocity of 60 kph?
