Question

At 20 mph the force of your car impacting a surface is about four times as great as 10mph. A True B. False

Answer 1

hello
the answer to this is its false

Answer 2

A True

Step-by-step explanation:

Kinetic energy (K.E) = 1/2 m v²

m is the mass and v is the velocity

K.E = 1/2×m×20² = 200 m

For the vehicle moving at 10 mph will be.

K.E = 1/2×m×10² = 50 m

Thus, is 200 m ÷ 50 m = 4 time greater.
