This question contains multiple parts: (a) to (b). A sprinter of mass 1001) kg accelerates from rest to 13.0 m/s on a flat track in 3 s. In the following treat the effect of air resistance to be negligible, Include units as appropriate (a) What is his power output (also called useful power out) during this time? P1: This question is a continuation from the previous question. A sprinter of mass 1000 kg accelerates from rest to 13.0 m/s on a flat track in 3 5. Treat the effect of air resistance to be negligible. Include units as appropriate. In part (a) we found the power output of the sprinter during a time interval of 3 s. (b) The sprinter trains by sprinting up a small incline' If he is to accelerate from rest to 130 m/s in 3 s on a grade of10\Rowan's and Jean's rates of energy consumption (which equals the power expended) doing various activities are given below. (Values from Table 75 in Urone and J, AppL PhysioL, 75, p2514-2520, 1993), Activity Rate of energy consumption sleeping 75 W sitting 110 W studying 120 W walking 280 W cycling 400 W Rowan Activity Rate of energy consumption sleeping 55 W sitting 95 W studying 105 W walking 280 W cycling 400 W Jean (3) What are Rowan's daily energy needs in both kJ and kcal if his day consists of sleeping for 8 hrs, walking for 2 hrs, studying for 10 hrs, cycling for 1,5 hrs and sitting for 2.5 hrs? Rowan's energy needs are H : kcal (b) What are Jean's daily energy needs in both kJ and kcal if her day also consists of sleeping for 8 hrs, walking for 2 hrs, studying for 10 hrs, cycling for 1.5 hrs and sitting for 2.5 hrs? Jean's energy needs are H kcal
