Answer:
option B is the correct option
Explanation:
According to momentum conversion,
momentum of one car= 6600×2=13,200kgm/s
momentum of another car=5,400×(-3)=16,200kgm/s
Then,
Momentum of second car-momentum of first car
=16,200-13200
=3000kgm/s
mass of first car -mass of second car
=6600-5400
=600kg
final velocity=3000/600=2.5 m/s
Answer:
μ = 0.109
Explanation:
Draw a free body diagram of the crate. There are four forces:
Weight force mg pulling down.
Normal force N pushing up.
Applied force P pulling at θ above the horizontal.
Friction force Nμ pushing to the left.
Sum of the forces in the y direction:
∑F = ma
N + P sin θ − mg = 0
N = mg − P sin θ
Sum of the forces in the x direction:
∑F = ma
P cos θ − Nμ = ma
P cos θ − ma = Nμ
μ = (P cos θ − ma) / N
μ = (P cos θ − ma) / (mg − P sin θ)
Given:
P = 585 N
θ = 28.0°
m = 125 kg
a = 3.30 m/s²
μ = (585 cos 28.0° − 125 kg × 3.30 m/s²) / (125 kg × 9.8 m/s² − 585 sin 28.0°)
μ = 0.109
Gravity ALWAYS does that, and electrostatic force does it when two objects have opposite charges.
