An iron robot falls from rest at a great height. neglecting air resistance, what is its speed after it has fallen for 3.5 second
algol13
In an uniformly accelerated motion, the velocity of the object follows the law:
v(t) = v_0 + at
where v_0 is the initial velocity, a the acceleration and t the time.

In our problem, the robot starts from rest, so the initial speed is zero: v_i =0. The robot is in free fall, so the acceleraion is the gravitational acceleration g=9.81 m/s^2. therefore, after a time t=3.5 s, the velocity is 
v(3.5 s)= 0 + (9.81 m/s^2)(3.5 s)=34.3 m/s

An object is going to the left at constant velocity. What is true? All forces acting on the object balance each other out. There
IgorLugansk [536]

Answer:

Net force of the object is zero.

Explanation:

When an object is going to the left at constant velocity, this means there is no acceleration. Hence, no force. Had there been force,acceleration had been inevitable. Therefore, we can say that when an object moves with a constant velocity and in same direction, the net force on the object is zero.

1.What is the kinetic energy of an object with a velocity of 7m / s and a mass of 14kg
Vlada [557]

Answer:

Explanation:

The formula for KE is

KE=\frac{1}{2}mv^2 and we fill in to solve for KE:

KE=\frac{1}{2}(14)(7.0)^2 I used 2 significant digits in the velocity because 1 isn't accurate enough. Therefore, my answer will be rounded to 2 sig fig's:

KE = 340 J (rounded from 343). And we do the exact same thing in #2:

KE=\frac{1}{2}(5.0)(5.0)^2 (Used 2sig fig's for both the mass and the velocity) to get

KE = 63 J (rounded from 62.5)
