Answer 1

Answer:

Explanation:

On Inclined plane !

___________________________________________________________

F = mgsinθ + μmgcosθ

Also , F = ma 

we get , 

ma = mgsinθ + μmgcosθ

a    = gsinθ + μgcosθ

a    = g(sinθ + μcosθ) 

a    = g(sin370 + 0.5 x cos370) 

a    = 10 (0.6 + 0.5 x 0.8) 

a    = 10 (0.6 + 0.4) 

a    = 10 x 1 = 10 m/s²

we know , 

v² - u² = 2 as 

final velocity (v)   = 0 (as it finally comes on rest ) 

initial velocity (u) = 20m/s 

acceleration (a)   = 10m/s²

v² - u²  = 2as 

s = v² - u² / 2a 

s = 0 - 20²/ 2 x 10 

s = -400 / 20 

s = -20 m (negative sign represent the direction)
