B) x=106t and 0=106t-5t^2
C) x=150t and 0=150t-5t^2

The impulse on the block due to force of gravity is 235.2 N.s

Explanation:

Given;

mass of the block, m = 3 kg

time of force of gravity action on the block, t = 8 s

Force of gravity on the block is given as;

F = mg

where;

m is mass of the block

g is acceleration due to gravity = 9.8 m/s²

F is the force of gravity

Substitute the given values and calculate F

F = mg

F = 3 x 9.8

F = 29.4 N

The Impulse on the block is given by;

J = Ft

J = 29.4 N x 8 s

J = 235.2 N.s

Therefore, the impulse on the block due to force of gravity is 235.2 N.s
