Answer:

KE= 656.25 J

Explanation:

KE= ?

m= 75 kg

v= 35 m/s

KE= 1/2 (75)(35)^2

KE= (37.5)(17.5)

KE= 656.25 J

Answer:

Part 1: 0.3789

Part 2: 746 J

Part 3: 2.162 kW

Explanation:

Part 1:

Eff= $1-\frac{1223}{1969}$

Eff= 0.378873 ≈ 0/3789

Part 2:

W= 0.3789(1969)

W= 746 J

Part 3:

$Power=\frac{W}{t}$

$Power= \frac{746}{0.345}$

Power= 2162.3188 Watts

2162.3188 W-----> 2.162 kW
