Explanation:
The initial horizontal speed is 39 m/s, and the initial vertical speed is 0 m/s.
v₀ₓ = 39 m/s
v₀ᵧ = 0 m/s
In the y direction:
Δy = 73 m
v₀ᵧ = 0 m/s
aᵧ = 9.8 m/s²
Find: t
Δy = v₀ᵧ t + ½ aᵧt²
73 = 0 + ½ (9.8) t²
t = 3.9 s
In the x direction:
v₀ₓ = 39 m/s
aₓ = 0 m/s²
t = 3.9 s
Find: Δx
Δx = v₀ₓ t + ½ aₓt²
Δx = (39) (3.9) + 0
Δx = 150 m
Answer:
1. 60 kg m/s

3. none they both have same momentum
Answer:
-0.04194 V
Explanation:
= Number of turns in outer solenoid = 330
= Number of turns in inner solenoid = 22
= Current in inner solenoid = 0.14 A
= Rate of change of current = 1800 A/s
= Vacuum permeability = 
r = Radius = 0.0115 m
Magnetic field is given by
The average magnetic flux through each turn of the inner solenoid is
Magnetic flux is given by
Mutual inductance is given by
The mutual inductance of the two solenoids is
Induced emf is given by
The emf induced in the outer solenoid by the changing current inthe inner solenoid is -0.04194 V
