Answer:
A. 58.8m/s
Explanation:
The acceleration due to gravity is 9.8 m/s², so the velocity after 6 seconds is ...
v = at
v = (9.8 m/s²)(6 s) = 58.8 m/s
Answer:
250 N
433 N
Explanation:
N = Normal force by the surface of the inclined plane
W = Weight of the block = 500 N
f = static frictional force acting on the block
Parallel to incline, force equation is given as
f = W Sin30
f = (500) Sin30
f = 250 N
Perpendicular to incline force equation is given
N = W Cos30
N = (500) Cos30
N = 433 N
