Answer:

Higher force would be required to stop 5 kg of ball

Explanation:

The force required to stop a moving object depends on its momentum.

The momentum for 8 kg of rolling ball is = 8 kg * 0.2 m/s = 1.6 kgm/s

The momentum for 5 kg of rolling ball is = 8 kg * 1.0 m/s = 5 kgm/s

Hence, momentum of 5 Kg ball is higher than the momentum of 8 Kg of ball

Hence, higher force would be required to stop 5 kg of ball

A car weighs 15,000 N, and its tires are inflated to a pressure of 190 kPa.How large is the area of the car's tires that are in
Elan Coil [88]
Pressure is the force applied perpendicular to a surface divided by the area of the surface. Therefore, from the given values, we can easily calculate the area by dividing the force to the pressure. We do as follows:

Area = F / P
Area = 15000 / 190000
Area = 0.0789 m^2

Hope this answers the question. Have a nice day.

A milk truck carries milk with density 64.6 lb/ft3 in a horizontal cylindrical tank with diameter 12 ft. (a) Find the force exer
7nadin3 [17]

Answer:

F = 351×10³lb

Explanation:

Given the density

ρg = 64.6lb/ft³

Diameter d = 12ft

The tank is horizontally cylindrical. The vertical distance from the top to the bottom of the tank is h = 12ft

The pressure in the tank is

P = ρgh = 64.6 × 12 = 775.2lb/ft²

The force exerted on one end of the tank is therefore F = PA = 775.2 × πd² = 775.2π×12²

F = 351×10³lb.
