Dale Earnhardt Jr.’s car can do 0–80 mph in 3.5 s. His weight is listed at 175 lb.
What force does Dale Earnhardt feel as he takes off from the line? Round the final answer to one decimal place.
Does the force felt by Dale Earnhardt point backward?
The formula for conversion is 1mph=0.4407m/s and 1lbs=0.4536kg.
The acceleration experienced by dale is given is given by the ratio of change in velocities to the change in time, i.e.
The force experienced by dale is his mass times the acceleration,
Dale feel a force of 800N in backwards direction due to inertia of his mass.
