Question

The average velocity of the vehicle is 180 km/hr. It requires 2000 W for operation of
30 min. Find the magnitude of constant tractive effort.
11 N
3 N
1 N
40 N

Answer 1

Answer:

40 N

Explanation:

Hey mate,

P= FX V

here, P = 2000W

v = 180 km/ hr = 50 m/sec

therefore substituting the values in the formula we get,

2000 = 50 X F

therefore,

F = 40 W.

Effort refers to force only in this case...
