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.
Reproduction-the ability of living organisms to reproduce.
Respiration- a process in living organisms involving the production of energy.
Answer: radio and television
Satellite orbits with an East-West orientation are best used
for communication purposes. The satellite orbit should always be suited for its
purpose. Radio and television are powered by numerous satellites rotating the
Earth from east to west.
Momentum (P) = Mass (kg) * Velocity (m/s)
P = M * V
P = 50 * 5
P = 250
So momentum is 250 kgm/s
Answer:
Each ribbon = 10 inches
Explanation:
Each yard = 36 inches
4 2/3 * 36 = 168 inches now cut off 8 inches
160 inches
now make 16 ribbons 160 / 16 = 10 inches
