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
F = MA (mass x acceleration)
F = (900) x (3) = 2700 kg-m/sec2 = 2700 newtons
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 8 m/s in 2 seconds. The net force acting on the body is
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.
Power = Force x displacement/time = 500 x 1000 / 120 = 4166.67 W
5,400
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.
No.
-530 (m+9) = 10.0
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.
it is the force that makes it skid when sudden breaking.
no
Resistance force.
The duration of Gall Force is 3600.0 seconds.
The duration of Voltron Force is 1800.0 seconds.
The duration of E.A.R.T.H. Force is 2700.0 seconds.
The duration of Lightning Force is 1800.0 seconds.
