First,from newton's second law,we can understand that F=m*a
We already know the mass,i.e 900mg,so we only need to convert the mass into k.g(to help in the calculation) and also find acceleration.
1mg=10^-6(0.000001)kg
900mg=?
then you cross multiply,the answer will be 9*10^-4 or 0.0009kg
now,to find acceleration,we use the formula
a=v-u v is equal to 0 because the car has come to a stop making
t
the final velocity o.
a=0-10ms
5s the final answer is -2ms
therefore, F=0.0009kg*-2ms making your last answer -0.0018N
the negative indicates that the force is against the motion of the car,so we can just cancel the negative and just say F=0.0018N or 1.8*10^-3

∙ 11y agoF = MA (mass x acceleration)
F = (900) x (3) = 2700 kg-m/sec2 = 2700 newtons

What is the objects velocity after the 20 N force is applied for 5 seconds?
There is no answer to your question without knowing the direction of the velocity and of the force application.
Starting from rest a 2 kg body acquires a speed of 8ms in 2 seconds the net force acting on the body is?
Starting from rest, a 2 kg body acquires a speed of 8 m/s in 2 seconds. The net force acting on the body is
What does it mean a less massive object will speed up more quickly than a more massive object subjected to the same force?
For example, if you push a canoe for 10 seconds with a certain force, and if you push an ocean liner for 10 seconds with the same force, the canoe will be moving faster, because it has less mass.

Direction is to the right. Magnitude is 10 Newtons.
What is the power if a force of 500 Newton moves a mass 1000 meters in 120 seconds?
Power = Force x displacement/time = 500 x 1000 / 120 = 4166.67 W

A car of mass of 900kg moves at 10 meters per second what is the braking force required to stop the car in a time of 5 seconds?
In order to stop the car within 5 seconds, it must have a negative acceleration (or deceleration) of -2m/s2. According to Newton's 2nd law: F = m*a. a = -2, m = 900kg, so F must be -1800N. Or 1800 Newtons to the direction reversed to the movement.
Are breaking strength and breaking force equal terms?
No.
A car of mass 900 kg moves at 10 ms what is the breaking force required to stop the car in a time of 5 seconds?
-530 (m+9) = 10.0
How was light created?
Light, photons or rather the electromagnetic force was created by a process called Electroweak symmetry breaking. This took place several seconds after the big bang.
