Answer : The value of momentum is and m = 3.735 and n = 7
Explanation : Given,
Mass of high speed train =
Velocity of train =
Formula used :
where,
p = momentum
m = mass
v = velocity
Now put all the given values in the above formula, we get:
Therefore, the value of momentum is and m = 3.735 and n = 7
Assume the downward direction is positive and upward direction is negative
W = weight of the object = 12 N
f = air resistance on the object = - 3 N
F = net force on the object
net force is the sum of forces acting on the object , hence the net forces is given as
net force = sum of forces
F = W + f
F = 12 + (- 3)
F = 12 - 3
F = 9 N
hence the size of net force on the object comes out to be 9 N
V= s/t = 400/4.5=800/9 (km/h)
Answer:
I would make all the people depressed but that would be normal and all the happy people were considerd sped.
