The force generated in 1 second of impact is, F = 201161.37 N

The ship slightly slows down and moves forward with velocity V = 9.9 x 10¹⁰ kg miles/hr

Explanation:

Given data,

The mass of the ship, M = 100 ton

= 100,000 kg

The velocity of the ship, V = 1,000,000 miles/hr

The mass of the iron piece, m = 1 lb

= 0.45 kg

The velocity of the iron piece, v = 0

The momentum of the ship,

P = MV

= 100,000 kg x 1,000,000 miles/ hr

= 1 x 10¹¹ kg miles/ hr

The momentum of the iron piece, p = 0

According to the conservation of momentum,

MV + mv = U(M + m)

$U=\frac{MV+mv}{M+m}$

$U=\frac{1\times 10^{11} +0}{100000+0.45}$

U = 999,995.5 miles/hr

Therefore the momentum of the ship after impact,

P₁ = MU

= 100,000 kg x 999,995.5 miles/hr

= 9.9 x 10¹⁰ kg miles/hr

Therefore, the change in the momentum of the ship,

ΔP = P - P₁

= 1 x 10¹¹ - 9.9 x 10¹⁰

= 449997.98 kg miles/hr

= 201161.37 kg m/s

Let the time period of impact be 1 s

Therefore, the force exerted by the ship on the iron is,

F = ΔP / t

= 201161.37 / 1

= 201161.37 N

Hence, the force generated in 1 second of impact is, F = 201161.37 N

The ship slightly slows down and moves forward with velocity V = 9.9 x 10¹⁰ kg miles/hr

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
