It’s to push an object in it’s direction of where it’s leading to.
Not sure if this is what your looking for, but hope it helps. Nitrogen gas can be changed into nitrogen compound through nitrogen fixation, which is the conversion of nitrogen gas to ammonia, that are absorbed by the plant to make protein. Another way is through animals eating plants and obtaining nitrogen, which is later released, by decomposes, when the organism dies.
speed of the car = 27 m/s
speed of truck ahead = 10 m/s
relative speed of car with respect to truck
relative deceleration of car
now the distance before they stop with respect to each other is given by
so it will come at the same speed of truck after 20.6 m distance and hence it will not hit the truck as the distance of the truck is 25 m from car
Part b)
Distance traveled by car before it stops is given by
so it will stop after it will cover total 52.1 m distance
Part c)
time taken by the car to stop
now the distance covered by truck in same time
now after the car will stop its distance from the truck is
<em>so the distance between them is 11.5 m</em>
Answer:
1.1x10^-2N
Explanation:
We have the change in momentum as
P = 0.3(4.5+12)g.mph
= 0.3x0.447x(4.5+12)x10^-3
Then the force that is exerted will be
F = p/∆t
∆t = 0.2
= 0.3x0.447x(4.5+12)x10^-3/0.2
= 0.1341x16.5x10^-3/0.2
= 1.1x10^-2
Therefore the force that was exerted is equal to 1.1x10^-2
Answer:
time=4, answer choice A
time=5.5, answer choice B
Explanation:
This is taken from the kinematic equation, v=vo+(1/2)at^2
Velocity at time 4 = 30+(2.5)(4)^2
Velocity at time 5.5 = 30+(2.5)(5.5)^2
Velocity at time 4 seconds = 70 m/s
Velocity at time 5.5 seconds = 105.63 m/s
