Answer:
1176 N
Explanation:
We are given that
Mass of car=1280 kg
Mass of trailer==350 kg
Car exerts a horizontal force against the ground =N
Coefficient of friction=
We have to find the force exerted by car on the trailer.
Substitute the values then we get
Force exert on the trailer
Hence, the car exerts force on the trailer=1176 N
Explanation:
Given:
x₀ = 0 m
v₀ = 4.2 m/s
t = 11.6 s
a = 2.3 m/s²
Find: x
x = x₀ + v₀ t + ½ at²
x = 0 m + (4.2 m/s) (11.6 s) + ½ (2.3 m/s²) (11.6 s)²
x ≈ 203 m
Round as needed.

Answer:
v = 22.68 10⁻³ m / s
vₓ = 5.32 10⁻³ m / s
, v_{y} = 22.08 10⁻³ m / s
Explanation:
Velocity is defined by
v = Δs / Δt
let's calculate for each axis
X axis
vₓ = (3.07 - 1.33) / 327
vₓ = 5.32 10⁻³ m / s
Y axis
= (4.33 - (- 2.89)) / 327
v_{y} = 22.08 10⁻³ m / s
the magnitude of the velocity can be calculated using the Pythagoras theorem
v² = vₓ² + v_{y}²
v = √ (vₓ² + v_{y}²)
v = √ (5.32² + 22.05²) 10⁻³
v = 22.68 10⁻³ m / s
