Question

A 650 KW power engine of a vehicle of
mass 1.5 * 105 Kg is rising on an inclined plane of inclination
1 in 100 with a constant speed of 60 km/hr. Find the frictional
force between the wheels of the vehicle and the plane. ​

Answer 1

Explanation:

Given A 650 KW power engine of a vehicle of mass 1.5 * 105 Kg is rising on an inclined plane of inclination  1 in 100 with a constant speed of 60 km/hr. Find the frictional  force between the wheels of the vehicle and the plane.

• Engine Power P = 650 KW = 6,50,000 W
• Mass of vehicle = m = 1.5 x 10^5 kg
• Inclination sin theta = 1/100
• Speed V = 60 km/hr = 60 x 5 / 18 = 50 / 3 m/s
• We need to find the frictional force.  
•           F = f + mg sin theta      (Now P = F V)
•        P/V = f + 1.5 x 10^5 x 10 x 1/100
•       6,50,000 x 3 / 50 = f + 15000
•         39,000 – 15,000 = f
•         Or f = 24,000 N
• So the frictional force between the wheels of the vehicle and the plane is 24,000 N
