Answer:
Explanation:
v² = u² + 2as
v = 0
u = 96 / 3.6 = 26.7 m/s
0² = 26.7² + 2a100
a = -3.5555555... ≈ -3.6 m/s²
the negative sign indicated the acceleration vector opposes the (assumed positive) initial velocity vector direction.

Answer:
13.18 m/s
Explanation:
Let the velocity of sports utility car is
 -u as it is moving in opposite direction.
mc = 1200 kg, uc = 31.1 m/s
ms = 2830 kg, us = - u = ?
Using conservation of momentum
mc × uc + ms × us = 0
1200 × 31.1 - 2830 × u = 0
u = 13.18 m/s
 
        
             
        
        
        
Answer:
q = 8.57 10⁻⁵ mC
Explanation:
For this exercise let's use Newton's second law
          F = ma
where force is magnetic force
          F = q v x B
the bold are vectors, if we write the module of this expression we have
          F = qv B sin θ
as the particle moves perpendicular to the field, the angle is θ= 90º
         F = q vB
the acceleration of the particle is centripetal
         a = v² / r
we substitute
         qvB = m v² / r
          qBr = m v
           q = 
The exercise indicates the time it takes in the route that is carried out with constant speed, therefore we can use
           v = d / t
the distance is ¼ of the circle,
           d =  
            d = 
we substitute
            v =   
            r =  
            
let's calculate
            r = 2 2.2 10-3 88 /πpi
 2 2.2 10-3 88 /πpi
            r = 123.25 m
          
let's substitute the values
            q =  7.2 10-8 88 / 0.6 123.25
7.2 10-8 88 / 0.6 123.25
             q = 8.57 10⁻⁸ C
Let's reduce to mC
            q = 8.57 10⁻⁸ C (10³ mC / 1C)
            q = 8.57 10⁻⁵ mC
 
        
             
        
        
        
In an open system such as a campfire, matter can lose particles, gain particles or exchange particles.
