Answer:

0 m/s

Explanation:

At the highest point, the vertical velocity is 0 m/s.

There's no horizontal velocity.

So the total velocity at the highest point is 0 m/s.

Which magnets need electric current for magnetism?

Arlecino [84]

Answer:An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor. Electromagnets have many uses.Permanent magnets are mainly used in small generators, and they have the advantage that they don't need a power supply. Electric magnets are iron or steel wound with wire. When electricity passes through the wire, the metal becomes magnetic and creates a magnetic field.

Consider the following equations of motion.

Helen [10]

A) No, the equations presented above are the product of the derivation of position and velocity when the acceleration is constant.

The equations change to polynomial function of the second degree for the description of the acceleration when described as a function of time.

B) Yes, when the acceleration is zero it is concluded that the velocity is constant, therefore they could be used to describe the position as a function of the change in velocity.

In a position time graph, a curved line represents: acceleration no movement constant velocity

xz_007 [3.2K]

A curved line on a position/time graph shows that the speed is changing.

So right there, we know there is acceleration.

Consider a mass initially moving at 7.50 m/s. How does it take to move 3.5 km (Be sure to convert to meters) if it accelerates a

Tomtit [17]

The mass is moving by uniformly accelerated motion, with initial velocity $v_i=7.50 m/s$ and acceleration $a=0.55 m/s^2$ . Its position at time t is given by the following law:
$x(t)=v_i t + \frac{1}{2}at^2$
where we take the initial position $x_i=0$ since we are only interested in the distance traveled by the mass.

If we put $x(t)=d=3.5 km=3500 m$ into the equation, the corresponding time t is the time it takes for the mass to travel this distance:
$\frac{1}{2}at^2+v_it-d=0$
$4.9t^2+7.5t-3500 =0$
And the two solutions for the equation are:
$t=-25.5 s$ --> negative, we can discard it
$t=24.0 s$ --> this is the solution to our problem
