Does increasing impulse means that theres less momentum?

1 answer:

4 0

in every collision there will be always an impulse I which represents change in momentum and is always constant. Thus, I = F x t = constant. Hence whenever, there is a change in impact ie force, there will also be equal change in time or vice versa. Thus, increae of time will decrease impact ie., force.

e.g., a person gets less injured on sand floor when compared to cemented floor when jumping from same height due to increase of time and decrease of force.

8. If the mass of a balloon is 300 kg and the lift force provided by the atmosphere is 3300 N, what

zmey [24]

Answer:

Toward the north, 300 N

Explanation:

Consider the upward direction as positive and downward direction as negative.

Given:

Mass of the balloon is, $m=300\ kg$

Lift force on the balloon in the upward direction is, $F_L=3300\ N$

Take acceleration due to gravity as 10 N/kg.

Now, weight of the balloon acting downward is given as the product of its mass and acceleration due to gravity. Therefore,

Weight is, $W=mg=(300\ kg)(10\ N/kg)=-3000\ N$

Now, net force is given as the vector sum of both the forces.

$F_{net}=F_L+W\\F_{net}=3300-3000=300\ N(\textrm{Upward direction})$

The upward direction is the direction of North. So, the net force acting on the balloon is 300 N towards North.

If The dimensions of a brick that weighs 25N are 0.19m x 0.07m x 0.095m. What pressure does the brick exert on the ground if it

valina [46]

1 newton per square meter = 1 pascal of pressure.

The largest face of the brick is (0.19 x 0.095) = .01805 square meter

25N/0.01805 = 1,385 newtons per square meter = 1,385 pascal = 1.385 kPa
