That completely depends on all sizes and all directions of all of the vectors that combined to produce the resultant one.
Hi there,
Matter is sometimes invisible. Most invisible matters are gas because it consists of tiny air molecules.
Hope this helps!

Answer: Cadence braking or Stutter braking is the braking technique slows the vehicle as quickly as possible without locking brakes or losing traction.
Explanation: To find the answer, we need to know more about the Cadence breaking.
<h3>What is cadence braking?</h3>
- It's a braking technique, that includes, pumping the brake pedal and which used to allow a vehicle to steer as well as brake on a slippery surface.
- It is used in the case of an emergency or sudden braking is needed.
- In this technique, traction is limited to reduce the effect of skidding from road wheels locking up under braking.
Thus, from the above given data, we can conclude that, Cadence braking or Stutter braking is the braking technique slows the vehicle as quickly as possible without locking brakes or losing traction.

Answer:
0.38 kN
Explanation:
From newton's second law of motion,
F = m(v-u)/t........................ Equation 1
Where F = Average force exerted on the ball, m = mass of the ball, v = final velocity of the ball, u = initial velocity of the ball, t = time of contact.
Given: m = 55 g = 55/1000 = 0.055 kg, v = 102 ft/s = (102×0.3048) m/s = 31.0896 m/s, u = 0 m/s (initially at rest), t = 0.0045 s
Substitute into equation 1
F = 0.055(31.0896-0)/0.0045
F = 1.709928/0.0045
F = 379.984 N
F ≈ 0.38 kN
Answer:
Given: mass 1200kg
initial velocity: 4m/s
finial velocity: 10 m/s
time 3 sec
then
speed; initial velocity + final velocity/2
4+10/3
: 4.66m/s2
