The car A and car B are travelling at different speeds. The car that has a greater acceleration is car B.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Car A is traveling with a constant velocity of 18 [m/s]. The initial and final velocity is same. So, the acceleration is given by
a = (18 -18)/ t
a = 0 m/s²
Car B speeds up from 0 [m/s] to 10 [m/s] in 4 seconds. The acceleration is
a = (10 -0)/ 4
a = 2.5 m/s²
Thus, the car B has greater acceleration.

Answer:
M₂ = M then L₂ = L
M₂> M then L₂ = \frac{M}{M_{2}} L
Explanation:
This is a static equilibrium exercise, to solve it we must fix a reference system at the turning point, generally in the center of the rod. By convention counterclockwise turns are considered positive
∑ τ = 0
The mass of the rock is M and placed at a distance, L the mass of the rod M₁, is considered to be placed in its center of mass, which by uniform e is in its geometric center (x = 0) and the triangular mass M₂, with a distance L₂
The triangular shape of the second object determines that its mass can be considered concentrated in its geometric center (median) that tapers with a vertical line if the triangle is equilateral, the most used shape in measurements.
M L + M₁ 0 - m₂ L₂ = 0
M L - m₂ L₂ = 0
L₂ = L
From this answer we have several possibilities
* if the two masses are equal then L₂ = L
* If the masses are different, with M₂> M then L₂ = \frac{M}{M_{2}} L
Answer:
a car could accelerate from 0 to 80 mph in 3.4 seconds.
Explanation:
It is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game.
<h3>
What is a motor crash?</h3>
A motor crash is the event in which a motor vehicle is involved in a collision amongst another motor vehicle, pedestrian, animal, or stationary object.
<h3>Impact of motor crash</h3>
A motor crash can cause the following;
- total damage of the car
- breaking of bones of the driver
- damage of properties colliding with the car
Thus, it is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game. In the video game he will not be involved physically with the motor crash.
