A 2 kg toy car moves at a speed of 5 m/s. a. What is the kinetic energy of the car?
b. If a child applies a 3 N force for 2 m in the same direction the car is already moving, how much work is done on the car?
c. What is the change in the car’s kinetic energy from the applied force?
d. What is the final kinetic energy of the car?
e. What is the velocity of the car after the child applies the 3 N force?

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.
