Answer:
170 N
Explanation:
F=pressure(pa) ÷ area(m^2)
=100.000 ÷ 0,0017
=<em><u>170</u></em><em><u> </u></em><em><u>N</u></em>
Answer:
If you use the same force to push a truck and a car, the car will have more acceleration than the truck because the car has less mass.
It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one. This means that more force is required to push the shopping cart.
When a person kicks a ball the person exerts force in a specific direction, that is the direction in which it will travel. In addition to this, the stronger the ball is kicked, the stronger the force we put on it and the further away it will travel.
Suppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.
When riding a bicycle, the bicycle acts as mass and our leg muscles pushing on the pedals of the bicycle is the force.
Explanation:
Answer:
33°
Explanation:
We are given;
Speed at which both snowballs are thrown; v = 33.2 m/s
Angle at which snowballs are thrown with respect to the horizontal; θ = 57°
Now,we want to find out the angle at which the second snowball should be thrown in order to arrive at the same point as the first.
To calculate this angle, we will use complementary angle concept.
Now, because the target is in the same place, there will be two launch angles that will make the snow ball to be placed on the target.
The is calculated from;θ1 = 45° - (57° - 45°) = 33°
Answer:
The answer is D.8s
Explanation:
We know,
![a=\frac{dv}{dt} \\=>adt=dv\\\\=>-0.5tdt=vdt ;[a=-0.5t]](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bdv%7D%7Bdt%7D%20%5C%5C%3D%3Eadt%3Ddv%5C%5C%5C%5C%3D%3E-0.5tdt%3Dvdt%20%3B%5Ba%3D-0.5t%5D)
.......(i)
For, t = 0, v = 16 ms⁻¹
t = x, v = 0 ms⁻¹;(the car stops)
Now, Definite integral for equation (i),
;[the lower limit will be 16 but I don't know why this is not working]
∴
hope you have understood this...
