Just after vertical launch from earth surface, the space shuttle takes 8.0 s to reach a speed of 160 km/h. during this phase, what is the apparent weight of an 84 kg astronaut?

1291.08 N

Explanation:

acceleration=change in speed per unit time

where v and u are final and initial velocities respectively.

u is zero and v=160 km/h converted to m/s becomes

acceleration=

Apparent weight,

Taking g as 9.81 and m as 84 Kg then

temp rises, and expansion

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.
