a net force of 1,800 N is applied to a boat causing it to accelerate at 1.5 m/s^2. what is the mass of the boat?
Xelga [282]

Answer:

<h3>The answer is 1200 kg</h3>

Explanation:

The mass of an object can be found by using the formula

m =  \frac{f}{a}  \\

f is the force

a is the acceleration

From the question we have

m =  \frac{1800}{1.5}  \\

We have the final answer as

<h3>1200 kg</h3>

Hope this helps you

A car undergoing uniform acceleration travels 100 meters from a standing start in a given period of time. If the time were incre
iogann1982 [59]

Answer:

d = 1600 m

Explanation:

If car start from rest and accelerates uniformly then the displacement of the car is given as

d = v_i t + \frac{1}{2}at^2

now we know

d = 0 + \frac{1}{2}at^2

now if the same car will accelerate from rest for four times of the previous time interval

then we will have

d = 0 + \frac{1}{2}a(4t)^2

d = 16(\frac{1}{2}at^2)

so the distance will be 16 times more

d = 1600 m
