Answer:

Option A

5 m/s^{2}

Explanation:

From fundamental equation of motion

v^{2}=u^{2}+2as where v is the final velocity, u is the initial velocity, a is the acceleration of the body and s is the displacement.

Since the initial velocity is zero

v^{2}=2as

Making acceleration, a the subject of the formula then

a=\frac {v^{2}}{2s}

Substituting 5 m/s for v and 2.5 m for s then

a=\frac {5^{2}}{2\times 2.5}=5 m/s^{2}

Answer:

Final speed of boat + man is 1.66 m/s

Explanation:

As we know that there is no friction on the system or there is no external force on this system

So here we can use momentum conservation here

mv = (m + M)v_f

so we have

m = 85 kg

M = 135 kg

v = 4.30 m/s

now we have

85 \times 4.30 = (85 + 135) v

v = 1.66 m/s

Give reason for the following observation
Irina-Kira [14]

Answer: The smell of hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close because the kinetic energy of the particles of matter increases with the increase in temperature. In cold foods, kinetic energy is less while in hot foods, kinetic energy is more

hope this helps
