Answer:
28,699m
Explanation:
The force to make the box move should be <u>μs.N=μs.m.g=m.</u><u>|</u><u>a</u><u>|</u>
then,
|a|=μs.g
Being
μs coefficient of static friction,
N the force made by the truck on the box caused by the gravity force,
m the mass,
g the acceleration of gravity
and a the acceleration of the truck.

as the truck is stopping, the acceleration is negative. then,





28,699m
Answer:
13.18 m/s
Explanation:
Let the velocity of sports utility car is
-u as it is moving in opposite direction.
mc = 1200 kg, uc = 31.1 m/s
ms = 2830 kg, us = - u = ?
Using conservation of momentum
mc × uc + ms × us = 0
1200 × 31.1 - 2830 × u = 0
u = 13.18 m/s
Answer:
c. find the slope of the velocity time graph
First I will parallel two of the resistors, creating a net 1 ohm. Then I will series that with the remaining 2-ohm resistor, resulting in 3 ohms.
D.
Have a longer revolution time since they definitely do not get warmer, They do not have fewer moons (Jupiter has about 100 and earth has 1) they are not smaller in diameter (Earth v Jupiter)
