Class 10 Force MCQ FM 20

When does a man exert more pressure on the floor: while standing or while walking?

 Pressure=Perpendicular Force/Area

Pressure = Thrust/area

While walking our one foot is contact with ground at a time, and while standing our two feet contact with ground, the surface area of one foot is less than two feet, and as surface area is less pressure will more, so while walking pressure is more. 

What should be the angle of banking of a circular track of radius 600m which is designed for cars at an average speed of 180km/h ? What will be the maximum velocity for a road with 10 degree banking and same curvature

 

A 3.0 kg fish is swimming at 1.5 m/s to the right. it swallows a 0.25 kg fish swimming to the left at 4.0 m/s. what is the speed and direction of the larger fish immediately after lunch?

 

A group of students are performing an experiment in class using collision carts on a track. An 8.0 kg cart moving to the right at 4.0 m/s hits a 4.0 kg cart moving to the left at 6.0 m/s. Immediately after the collision, the 4.0 kg cart moves to the right at 3.0 m/s. What are the speed and direction of the 8.0 kg cart after the collision?
