Aforce of 38.7 n is applied to the master cylinder of a hydraulic brake system. the cylinder has an area of 7.61 cm^2. the force from the master cylinder is transferred, by brake fluid, to two brake cylinders that have a total area of 49.1 cm^2. how much total force is exerted by the brake cylinders?

answer:

answer:

this is science right?

explanation:

a) (momentum of the elephant), p1 = 14625 kg×m/s

b) p1 = 609.4×p2

c) (momentum of the hunter), p3 = 720 kg×m/s.

Explanation:

a) if m = 1950 kg is the mass of the elephant and V = 7.50 m/s be the speed of the elephant, then the momentum is given by:

p1 = m×V = (1950)×(7.50) = 14625 kg×m/s

b) if m = 0.0400 kg is the mass of the bullet and v = 600 m/s be the speed of the bullet, then the momentum of the bullet is given by:

p2 = m×v = (0.0400)×(600) = 24 kg.m/s

then:

p1/p2 = (14625)/(24) = 609.4

that is, p1 = 609.4×p2

Therefore, the momentum of the elephant is 609.4 times the momentum of the bullet.

c) the momentum og the hunter after missing the elephant is given by:

p3 = m×v = (90.0)×(8) = 720 kg.m/s

Therefore, the momentum of the hunter is 720 kg×m/s.
