= 8.0
= 3.0
a) By Newton's Law,
∑
∑
Hence,
b) By Newton's Law
∑
Hence,
Net force acting on 100 kg mass,
Answer:
b
Explanation:
b. Culture bc Americans tend to have a more individualist orientation (focusing more on personal goals), while many Asians tend to have a
collectivist orientation (focusing more on family and work goals).
If the car is accelerating uniformly then,
velocity of car at the fourth second is 16m/s
Then if the car with this velocity stopped after 2s then acceleration is,
a=0-16/2=-8m/s^2
braking distance is given by
d=16*2-0.5*8*2*2
=32-16
=16m
this answer is valid only if the motion is one dimensional
all the best.
