Answer:
3: force acting on an object over time
Explanation:
The impulse formula is: change in momentum = force x time
Δp = f x t
Answer:
8.436 Nm
16.872 Nm
0
Explanation:
When we multiply the force with the distance at which the force is being applied we get torque
where
F = Force = 111 N
r = Distance = 0.152 m
= Angle at which force is applied
When,
The torque is 8.436 Nm
When,
The torque is 16.872 Nm
When,
The torque is 0
Newton's law of universal gravitation:
F = GMm/r²
F = gravitational force, G = gravitational constant, M and m are the masses, r = distance between the masses
Given values:
F = 4.24×10⁻¹⁰N, G = 6.67×10⁻¹¹Nm²kg⁻², M = m = 29kg
Plug in and solve for r:
4.24×10⁻¹⁰ = 6.67×10⁻¹¹(29)(29)/r²
r = 11.5m
Answer:
a = 3.33 m/s²
Explanation:
The horizontal acceleration of the dog can be found by using Newton's Second Law of Motion as follows:
F = ma
where,
F = Unbalanced force applied on the dog = 11 N - 10 N = 1 N
m = mass of the dog = 0.3 kg
a = horizontal acceleration of dog = ?
Therefore,
1 N = 0.3 kg(a)
a = 1 N/0.3 kg
<u>a = 3.33 m/s²</u>
