Momentum and CollisionHard
Question
After scaling a wall of 3 m height a man of weight W drops himself to the ground. If his body comes to a complete stop is 0.15 s. After his feet touch the ground, calculate the average impulsive force in the vertical direction exerted by ground on his feet.
Options
A.5W
B.5.21W
C.3W
D.6W
Solution
Velocity before strike
Impulse = Fᐃt = m(v - u)
⇒ F =
= 5.21 W
Impulse = Fᐃt = m(v - u)
⇒ F =
= 5.21 WCreate a free account to view solution
