Many things can affect a material's resistance, The type of material, how the material is being held (If its laying flat, being pulled, etc). What the material is used for, and how much material there is. Hope this helps!
Answer:
0. 1226495726kg
Explanation:
Force is the product of mass and acceleration.
Mathematically,
Force(F) = mass (m)×acceleration(a)
Substituting the values into the equation
2. 87=m×23. 4
2. 87=m (23. 4)
2. 87/23. 4=m (23. 4)/23. 4
2. 87/23. 4=m
0. 1226495726=m
Answer:
0.29 m/s due west.
Explanation:
According to newton's second law,
Net force acting on an object = mass×acceleration
From the question,
F+F₁+F₂ = ma................ Equation 1
Where F = The force generated from the engine, F₁ = Force exerted by the wind, F₂ = Force exerted due to the water, m = mass of the boat, a = acceleration of the boat.
Given: F = 4080 N , F₁ = -680 N(east), F₂ = -1160 N(east). m = 7660 kg
substitute into equation 1
4080-680-1160 = 7660(a)
2240 = 7660a
Therefore,
a = 2440/7660
a = 0.29 m/s due west.
