Answer:
110 m
Explanation:
Draw a free body diagram of the car. The car has three forces acting on it: normal force up, weight down, and friction to the left.
Sum of the forces in the y direction:
∑F = ma
N − mg = 0
N = mg
Sum of the forces in the x direction:
∑F = ma
-F = ma
-Nμ = ma
Substitute:
-mgμ = ma
-gμ = a
Given μ = 0.40:
a = -(9.8 m/s²) (0.40)
a = -3.92 m/s²
Given that v₀ = 30 m/s and v = 0 m/s:
v² = v₀² + 2aΔx
(0 m/s)² = (30 m/s)² + 2 (-3.9s m/s²) Δx
Δx ≈ 110 m
Answer:
By applying a force of one Newton, one can hold a body of mass of 102 gram.
Explanation:
- Force is the pull or push of an object. It can be mathematically measured as, F= m* g.
where, F= force in newton
m= mass in kg
g= acceleration due to gravity (
)
F= m* 9.8
or, m= 
= 0.102 kg
or, m= 102 gram.
- Hence, 102 gram mass can be hold by one Newton force.
