Answer:

b) 18 m/s is the correct answer.

Explanation:

initial velocity(u) = 30m/s

acceleration(a) = -4m/s²

time(t) = 3 seconds

final velocity(v) = ?

using the formula,

a = (v-u)/t

or, -4 = (v-30)/3

or, -12 = v-30

or, v = -12+30

so, v = 18 m/s

Two forces Upper FSubscript Upper A Baseline Overscript right-arrow EndScripts and Upper FSubscript Upper B Baseline Overscript
Pavel [41]

Answer:

Part a)

F_A = 4.59 N

Part B)

F_B = 1.28 N

Explanation:

As we know that when both the forces are acting on the object in same direction then we will have

F_A + F_B = ma

as we know that

a = 0.554 m/s^2

m = 10.6 kg

now we will have

F_A + F_B = 10.6(0.554)

F_A + F_B = 5.87 N

Now two forces are in opposite direction then we have

F_A - F_B = 10.6(0.313)

F_A - F_B = 3.32 N

Part A)

Now we will have from above two equation

F_A = 4.59 N

Part B)

Similarly for other force we have

F_B = 1.28 N
