Question

a block weighing 200 n is pulled up a 30° plane by a force P producing a velocity of 5 m/sec in 5 second.if the coefficient of friction is 0.2 , determine the magnitude of force p. at this​

Answer 1

Answer:

0.58

Explanation:

For vertical equilibrium, N=200−100sin30

0

=150N

For horizontal equilibrium, f=100cos30

0

f=μN

μ=

150

100cos30

0

μ=0.58
