Answer:
190 m/s
Explanation:
Acceleration = Force/ mass
a = F/m........................ Equation 1
Where F = force, m = mass of the space probe.
Given: m = 20 kg,
F(t) = 6.00t²
when t = 10 s.
F = 6.00(10)²
F = 600 N
Substituting these values into equation 1
a = 600/20²
a = 30 m/s.
But.
a = (v-u)/t
Where a = acceleration of the body, v = final velocity of the body, u = initial velocity of the body, t = time.
making v the subject of the equation,
v = u+at..................... Equation 2
Given: a = 30 m/s², u = 40 m/s, t = 5.00 s.
v = 40 + 30(5)
v = 40+150
v = 190 m/s
Thus the velocity of the space probe = 190 m/s
The velocity of larger piece=.
<h3>What is called a circular?</h3>
A circular is just a letter with important information that is widely distributed. If, for example, you need to change the workplace's dress code or invite a whole department to a conference, a circular will be the most effective form of communication. Since the original intent of a leaflet or newspaper supplement was for it to circulate—to spread among a group of people—it is referred to as a "circular.
When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.
Let the mass of the satellite before explosion = 5M.
According to the conservation of movement
The velocity of the satellite before the explosion.
= velocity of M mean.
= velocity of 4M mean.
Since, =0 (A.C.Q)
The velocity of larger piece=.

Answer: 10 kg
Explanation:
Kinetic Energy = 1/2 * M (V square )
M is mass and V is velocity of the ball
500J = 1/2 *M *( 10)*(10)
M = 10 kg
I think the answer is D
Hope this helps
The molecules will most likely move faster. So, the answer to this question is the first answer choice.
