Question

(A) When a force is applied to an object with mass equal to the standard kilogram, the acceleration of the mass is 3.25m/s^2 (Assume that friction is so small that it can be ignored.) When the same magnitude force is applied to another object, the acceleration is 2.75m/s^2. What is the mass of this object?

Note that x^2 is the format for entering squared values such as x2for units in the Learn system.

(B) What would the second object's acceleration (in previous Question) be if a force twice as large were applied to it?

(C) Given an object with mass equal to the standard kilogram, how would you determine if force applied to it equal to one newton? (Assume that frictional forces are so small that they can be ignored.)

(1)The object moves with an acceleration of 10m/s^2 when applying 1N force.

(2)The object moves with an accleration of 9.81m/s^2 when applying 1N force.

(3)The object moves with an accleration of 1/10m/s^2 when applying 1N force.

(4)The object does not move with 1N force.

(5)The object moves with an acceleration of 1m/s^2 when applying 1N force on it.

(1)The object moves with an acceleration of 10m/s^2 when applying 1N force.

(2)The object moves with an accleration of 9.81m/s^2 when applying 1N force.

(3)The object moves with an accleration of 1/10m/s^2 when applying 1N force.

(4)The object does not move with 1N force.

(5)The object moves with an acceleration of 1m/s^2 when applying 1N force on it.

Explanation / Answer

a)

F = ma

Hence

F = 1 * 3.25

F = 3.25 N

Now

3.25 = 2.75*m

m = 1.182 Kg

b)

If F = 6.5

And m = 1.182

F = ma

6.5 = 1.182*a

a = 5.499

c) Option 5
