A1,200 kg car is accelerated at 3.7 m/s2. what force was needed to produce this acceleration? a. 4,440 n b. 324.3 n c. 4,388 n d. 304.3 n

A. 4,440 N

Explanation:

A Force applied on an object with mass 'm' can change its velocity in a unit time. This change is called acceleration.

If a force 'F' is applied on a body of mass 'm', it produces an acceleration 'a' in the body.

Force is give as :

F = ma

In our case,

m = 1200 kg    a = 3.7 m/s²

F = 1200 x 3.7

F = 4440 kgm/s²

F = 4440 N

c)as speed changes, wavelength and frequency change.

everything changes!

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
