What is the magnitude of force required to accelerate a car of mass 1.7 × 10³ kilograms by 4.75 meters/secondæ?
a. 3.6 x 10 ^3 n
b. 1.7x10^3 n
c. 8.1x10^3 n
d. 9.0x10^3 n

Magnitude of force is

Explanation:

It is given that,

Acceleration of car,

Mass of car,

We have to find magnitude of force. It is given by using Newton's second law of motion which states that force is given by the product of mass and acceleration :

F = m a

or

Hence, the correct option is (c)

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
