A car moves with a constant speed a distance 12.6 km in 15 min. what is the car’s speed in metres of per second hlp!
150
203
Ответы на вопрос:
If it is a smooth motion, then the speed can be found by the formula (minutes turn into hours, 15 minutes = 0.25 hours):
12,6/0,25=50,4
Объяснение:
Скорость равна v = 7200 / 3600 = 2 м/с. дальность полёта при горизонтальном броске: l = v*√(2h/g) = 2*√(2*0,8/10) = 2*√0,16 = 2*0,4 = 0,8 м.
