Answer:
Impulse of force = -80 Ns
Explanation:
<u>Given the following data;</u>
Mass = 50kg
Initial velocity = 1.6m/s
Since she glides to a stop, her final velocity equals to zero (0).
Now, we would find the change in velocity.
Substituting into the equation above;
Change in velocity = 0 - 1.6 = 1.6m/s
Substituting into the equation, we have;
<em>Impulse of force = -80 Ns</em>
<em>Therefore, the impulse of the force that stops her is -80 Newton-seconds and it has a negative value because it is working in an opposite direction, thus, bringing her to a stop. </em>
You have to add 1.7 and 2.2 together!
1.7+2.2=3.9μF
mass of the box = 20 kg
force of friction on the box due to surface



similarly kinetic friction on it



now the weight of the suspended block will be

so here the weight of the suspended block is less than the limiting friction on it
So here we will say that friction will counter balance the weight of the suspended block and it will not move at all
So acceleration of the box will be zero
Answer: information in picture below hope u understand.
Explanation:
The acceleration will be 1.9166 m/s². According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
<h3>What is acceleration?</h3>
The rate of change of velocity with respect to time is known as acceleration.
Given data:
u(Initial velocity)=2.50m/s
v(Final velocity)=8.25m/s
t(time period)= 3.00s
The acceleration of the Allura will be :

Hence, the acceleration will be 1.9166 m/s².
