لدي سؤال واتمنى ان تسطيعوا الاجابة عليه
A spaceship ferrying workers to moon base i takes a straight-line oath from the earth to the moon, a distance of 384000 Km. Suppose it accelerates at 20 m/s2 for the first 15 min of the trip, then travels at constant speed until the last 15 min, when it accelerates at -20 m/s2 , just coming to rest as it reaches the moon.
a- what fraction of the total distance is traveled at constant speed
b- what total time is required for the trip
