Two snowcats tow a housing unit to a new location at McMurdo Base, Antarctica, as shown in the figure. The sum of the forces $F}_{A$ and $F}_{B$ exerted on the unit by the horizontal cables is parallel to the line L, and ${F}_{A}=4200$ N. Determine $F}_{B$? Determine the magnitude of $F}_{A}+{F}_{B$?

A 15.0 kg block is dragged over a rough, horizontal surface by a70.0 N force acting at 20.0 degree angle above the horizontal. The block is displaced 5.0 m, and the coefficient of kinetic friction is 0.3. Find the work done on the block by ; a) the 70.0 N force,b) the normal force, and c) the gravitational force. d) what is the increase in the internal energy of the block-surface system due to friction? e) find the total change in the kinetic energy of the block.

A projectile is shot from the edge of a cliff 125 m above ground level with an initial speed of 65.0 m/s at an angle of 37 degrees with the horizontal. (a) determine the time taken by the projectile to hitthe point P at ground level. (b) determine the range X of the projectile as measured from the base of the cliff at the instant just before the projectile hits point P. Find (x) the horizontal and vertical components of its velocity and (d) the magnitude of the velocity and (e) the angle made by the velocity vector with the horizontal (f) Find the maximum height above the cliff top reached by the projectile.

A particular die thrown a 100 times. The results are as follows:

x 1 2 3 4 5 6

frequency 12 20 27 21 14 6

a) Calculate the sample mean X̅, i.e. the average score you expect when throwing a single die

b) Calculate the corresponding sample standard deviation s

c) Now this experiment is conducted again 35 times. Assuming that the die indeed follows a

distribution with corresponding mean and variance found in a) and b), find the probability that

the sample mean, i.e. the average score of these 35 experiments, exceeds 4.

According to one survey in India, 75% of Instagram users love REELS. Suppose that 25

Instagram users (randomly selected) have been approached in the university located in vile

parle. They have been asked about their status of like/ dislike the Instagram- REELS.

a) What is the probability that Exactly 15 of them would agree with the claim (or said they

love Insta-REELS)?

b) What is the probability that Exactly 20 of them would agree with the claim (or said they

love Insta-REELS)?
