Given:

mass (m) = 1.5 kg ,

velocity (v) =2 m/s ,

time (t) = 0.30s ,

magnitude of net force (Fnet) = m. a

                                                =  1.5 × (v/t)           since a = v/t

                                                = 1.5 × (2/0.30)

                                                = 10 N

<em>Magnitude of net force is 10 N</em>

lesya [120]
No, because the distance-time would show a constant velocity but the velocity-time graph shows an increasing velocity.

If 5kg Stone and 1kg stone throw the from the building which will land more fa ster and why?​
sweet [91]

Answer:

Both stones will land at the same time because both stones will fall with the same acceleration through the same height.

Explanation:

We are given that

Mass of stone ,m1=5 Kg

Mass of stone, m2=1 kg

We have to find which stone more faster will land and why.

h=u+\frac{1}{2}gt^2

Initial velocity of both stones=0

h=\frac{1}{2}gt^2

t^2=\frac{h}{g}

t=\sqrt{\frac{h}{g}}

t_1=t_2=\sqrt{\frac{h}{g}}

Because both stones are thrown from the same height.

Both stones will land at the same time because both stones will fall with the same acceleration through the same height  and the acceleration  does not depend of its mass.
