You need to give the measurements
Answer: - 7500N
Explanation:
Given the following :
Initial Velocity of car = 108km/hr
Time taken to stop after applying brakes = 4s
Mass of passengers in car = 1000kg
Force exerted by the brakes on the car =?
After 4s, then final Velocity (V) = 0
Initial Velocity (u) of the car = 108km/hr
108km/hr = (108 × 1000)m ÷ (3600)s = 30m/s
Force exerted = mass(m) × acceleration(a)
Acceleration of car = Change in Velocity with time
a = (v - u) / t
a = (0 - 30) / 4
a = - 30/ 4
a = - 7.5m/s^2
Therefore,
Force exerted = mass(m) × acceleration(a)
Force exerted = 1000kg × (-7.5)m/s^2
Force exerted = - 7500N
5ft is two times the 10ft
<span>In the context of the verb take acquire double meaning. what are the senses. Thats what your saying in spanish right?. that has nothing to do with physics, thats english! JS.
Whats your question?
</span>
Aluminum has 3 valence electrons.
<span>You can figure out the valence electrons by looking at its group number. Aluminum is in group 3, so it has 3 valence electrons.
