Concept explainers
Toby Toobad, who has a mass of 100 kg, is skateboarding at 9.0 m/s when he smacks into a brick wall and comes to a dead stop in 0.2 s. Show that his deceleration is
To show: Deceleration of person T is 45 m/s2.
Explanation of Solution
Given:
Mass of person T,
Time,
Initial velocity,
Final velocity,
Formula Used:
From the equation of motion
Where,
Calculation:
On substituting the given values,
As acceleration is negative, it means deceleration is 45 m/s2.
Conclusion:
Therefore, it is proved that the deceleration of person T is 45 m/s2.
