I believe I seen on google if you go to Mather
<h2>
Velocity at maximum height is zero.</h2><h2>Acceleration at maximum height is 9.81 m/s² downward.</h2><h2>Acceleration when it just hits the ground is 9.81 m/s² downward.</h2>
Explanation:
For a ball thrown vertically upward, the velocity at maximum height is zero.
Acceleration is a constant for a ball thrown vertically upward, its is acceleration due to gravity.
Acceleration at maximum height is 9.81 m/s² downward.
Acceleration when it just hits the ground is 9.81 m/s² downward.
Answer:
The speed of the vehicles immediately after the collision is 5.84 m/s.
Explanation:
The speed of the vehicles after the collision can be found by conservation of linear momentum:
Where:
m₁: is the mass of the car = 0.5 ton = 500 kg
m₂: is the mass of the lorry = 9.5 ton = 9500 kg
: is the initial speed of the car = 40 km/h = 11.11 m/s
: is the initial speed of the lorry = 20 km/h = 5.56 m/s
: is the final speed of the car =?
: is the final speed of the lorry =?
Since the two vehicles become tightly locked together after the collision = :
Therefore, the speed of the vehicles immediately after the collision is 5.84 m/s.
I hope it helps you!
