A2200 kg truck has put its front bumper against the rear bumper of a 2400 kg suv to give it a push. with the engine at full power and good tires on good pavement, the maximum forward force on the truck is 18,000 n.
1. what is the maximum possible acceleration the truck can give the suv?
2. at this acceleration, what is the force of the suv’s bumper on the truck’s bumper?

Answer

given,

mass of truck (m_t)= 2200 Kg

mass of SUV (m_s)= 2400 Kg

Maximum forward force on the truck = 18,000 N.

a)

 both the body will be considered as a system

b) Force of the SUV’s bumper on the truck’s bumper

  F = m_s a

  F = 2400 x 3.91

  F = 9384 N

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.  

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
