The magnitude of an impulse produced by a 300 g mass rubber ball, striking a wall horizontally at a velocity of 40 m/s, that reb

8090 [49]

Option a. The total force that is calculated is given as 24 n/s

<h3>How to solve for the magnitude</h3>

300 g = 0.3kg

Force = change in momentum / time

We have to find the mass x velocity

0.3 x 40 = 12kg m / s

This rubber ball is said to strike and also rebound immediately. We can take the time as 1 second.

Force 1 x 12

= 12 N

The force that is exerted after the rebounding has occurred is also 12 N following Newton's 3rd law.

The total force that is exerted would be calculated as 12N + 12N = 24 N/S

A group of campers walked at a speed of 4. 5 mph from their campsite to a rest area. Their return trip to the campsite took 15 m

tia_tia [17]

The distance between the campsite and the rest area is 9 miles.

The given parameters:

Initial speed of the campers, u = 4.5 mph
Final speed of the campers, v = 4 mph

Let the time of motion from the campsite to rest area = t (hours)

Time for return trip = t hours + 15 mins

= (t + 0.25) hours

Let the distance between the campsite and rest area = d

d = 4.5t

d = 4(t + 0.25)

4.5t = 4(t + 0.25)

4.5t = 4t + 1

4.5t - 4t = 1

0.5t = 1

t = 2 hours

The distance between the campsite and the rest area is calculated as follows;

d = 4.5t

d = 4.5 x 2

d = 9 miles

Thus, the distance between the campsite and the rest area is 9 miles.

Dear uncle, 

 

 I am fine and happy here though specific things are challenging. I am writing this letter to you to tell you my experiences. 

I don't know what happened to me suddenly. I never used to like maths or physics before in 9th. I had developed intersted and love towards physics and maths. The teachers of math and physics are awesome too. I don't know how I have changed this much. But there are some problems I an facing . I don't like social and biology because they are very hard to learn but physics and mathematics are very easy. I am confused in the topic of subject choice for 11th grade. Anyways, I hope to hear from you very soon. Please give me some tips too. 

Convery my regards to aunt and cousins. 

 Your lovingly, 

 Name of yours,
