Answer:
yes, because you guy's are moving in a car. because if you think about it, your parents are driving, but the cars moving so basically you guys would be moving.
please mark as brainly
Answer:
-50 N
Explanation:
Givens:
V_i = 36 km/h
V_f = 18 km/h
t = 2 s
m = 20 kg
First we have to convert our km/h into m/s:
(36 km*(1000 m/1 km)) / (60 min *(60 s/1 min)) = 10 m/s
(18 km*(1000 m/1 km)) / (60 min *(60 s/1 min)) = 5 m/s
a = (V_f - V_i)/t
a = (5 m/s - 10 m/s) / 2 s
a = -2.5 m/s^2
F = m(a)
F = 20 kg(-2.5 m/s^2)
F = -50 N
It's a negative force meaning its acting on it opposite its current direction of movement.
Answer:
Explanation:
ratio of the forces is equal to the ratio of the surface areas
which is another way of saying the pressure is constant in the system
2000(9.8) / 500 = A / 10
A = 2000(9.8)(10) / 500 = 392 cm²
One divides the volume by the density. You get
(or one liter, if you want)
