Question

Q2. If a truck covers 180 km in in one and half hour then how much distance it will covers in 36 minutes​

Answer 1

The frictional force always act at the contact point of ball and inclined plane, while the gravity force acts at center of mass/gravity. Both the force are not in one line, they have a radius (R) distance between them, incase of a ball. This creates torque, which results in rotational motion; i.e. Rolling.

Answer 2

Answer:

72 km

Step-by-step explanation:

We are given 180 km in one and half hour

one and half hour = 60+30 = 90min

Distance travelled in 1 minute

180/90 = 2kmpm

Distance travelled in 36 minutes

2*36 = 72km
