How much impulse is applied by a 25 N force in 30 seconds?
Answers
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Impulse.
Impulse is denoted by 'J'
hence, J = F. dt
so we get as,
J = (25)*(30)
J = 750 N-s
===> hence the impulse is 750 N-s
Impulse is applied by a 25 N force in 30 seconds is 750 N-s.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

10-kg box is sliding across an ice rink at 10 m/s . A skater exerts a constant force of 10 N against it. How long will it take for the box to come to a complete stop?
Answers
Answer:
Time, t = 10 seconds
Explanation:
Given the following data;
Mass = 10kg
Force = 10N
Final velocity = 10m/s
Initial velocity = 0m/s
To find the time;
First of all, we would find the acceleration of the box.
Force = mass * acceleration
10 = 10 * acceleration
Acceleration = 10/10 = 1m/s²
Now, we can find the time by using the first equation of motion;
V = U + at
10 = 0 + 1t
10 = t
Time, t = 10 seconds
Therefore, it will take 10 seconds for the box to come to a complete stop.

A car travels along a straight road to the east for
100 meters in 4 seconds, then has to turn around
and goes back west for 50 meters in 1 second.
Determine average speed and average velocity.
Answers
Answer: 90 m/s, 70 m/s
Explanation:
Given
A car travels 100 m east for 4 seconds and then turn around
goes back west for 50m in 1 sec
Distance traveled in the east is [tex]100\times 4=400\ m[/tex]
Distance traveled in the west is [tex]50\times 1=50\ m[/tex]
Total distance[tex]=400+50=450\ m[/tex]
total displacement[tex]=400-50=350\ m[/tex]
total time [tex]t=4+1=5\ s[/tex]
Average speed
[tex]\Rightarrow s_{avg}=\dfrac{\text{distance}}{\text{time}}=\dfrac{450}{5}\\\\\Rightarrow s_{avg}=90\ m/s[/tex]
Average velocity
[tex]\Rightarrow v_{avg}=\dfrac{\text{displacement}}{\text{time}}=\dfrac{350}{5}\\\\\Rightarrow v_{avg}=70\ m/s[/tex]

An old woman is worried about time. She walks at a rate of 2 meters per second and travels a
distance of 454 meters. How long does it take her to complete the motion?
Please help ASAP!! BRAINLIST please explain thankyou!!!
Answers
Answer:
227 seconds.
Explanation:
Speed is equal to distance divided by time. s = d/t
We can rearrange this algebraically to solve for the time it will take to cover a certain distance at a certain speed. Time is equal to distance divided by speed. t = d/s
Then we substiture our known values for the variables and solve for our unknown.
t = 454m / 2m/s = 227s
Answer:
If the lady is traveling 2 meters per second and she travels 454 meters then you will have to divide 454 by 2 to get the amount of time she walked.
454 divided by 2 = 227
This means that the lady traveled for 227 seconds or about 3.78 minutes.
