If the coefficient of friction between his clothes third base. He starts a and the surface of the baseball infield is 0.60, determine the folowing.

Explanation / Answer

Here ,

m = 71 Kg

v = 4.3 m/s

u = 0.60

a)

mechanical energy lost = 0.50 * m * v^2

mechanical energy lost = 0.50 * 71 * 4.3^2

mechanical energy lost = 656.4 J

b)

a = u * g

a = 0.60 * 9.8

a = 5.88 m/s^2

let the distance is d

Using third equation of motion

4.3^2 = 2 * d* 5.88

solving for d

d = 1.57 m

the distance needed is 1.57 m
