Three 500-g point masses are at the corners of an equilateral triangle with 50-cm sides. What is the moment of inertia of this s

Ede4ka [16]

Answer:

0.25 kg m^2

Explanation:

mass of each , m = 500 g = 0.5 kg

distance, r = 50 cm = 0.5 m

Moment of inertia about the axis passing through one corner and perpendicular to the plane of triangle

I = mr^2 + mr^2

I = 2 mr^2

I = 2 x 0.5 x 0.5 x 0.5

I = 0.25 kgm^2

A car has a mass of 1,200 kg. What is its acceleration when the engine exerts a force of 600 N? (Formula: F=ma) 0.5 m/s2 2 m/s2

schepotkina [342]

As per the question the car has a mass of 12,00 kg.

The engine exerts a force of 600 N. [ here newton i.e N is the unit of force]

We are asked to calculate the acceleration of the particle .

From Newton's second law of motion we know that force acting on a particle is mass times the acceleration of the particle . Mathematically it can be written as-

F = ma [Here F is the applied force,m is the mass which is constant here and ' a' is the acceleration]

Here m =1200 kg

F = 600 N

Hence the acceleration produced due to the force exerted by the engine on car is-

$a =\frac{F}{m}$
