A small boat is crossing a lake on a windy day. During some interval of time, the boat undergoes the given displacement AP AF (3.19 m)i +(2.75 m)j During the same interval of time, the wind exerts the given constant force F on the boat. F= (255 N)i-(127 N)j What is the total work done on the boat by the wind over this period of time? work: What is the angle between the direction of the wind force and the...

Thank you
319-kg boat is sailing 14.5° north of east at a speed of 1.84 m/s. Thirty seconds later, it is sailing 33.9° north of east at a speed of 4.12 m/s. During this time, three forces act on the 34.2-N force directed 14.5° north of east (due to an auxiliary engine), a 23.5-N force directed 14.5° south of west (resistance due to the water), and Fw (due to...

A 321-kg boat is sailing 10.0° north of east at a speed of 2.00 m/s. 30.0 s later, it is sailing 33.0° north of east at a speed of 4.10 m/s. During this time, three forces act on the boat: a 32.3-N force directed 10.0° north of east (due to an auxiliary engine), a 23.9-N force directed 10.0° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of...

An unsuspecting bird is coasting along in an easterly direction at 1.00 mph when a strong wind from the south imparts a constant acceleration of 0.300 m/s^2. If the acceleration from the wind lasts for 2.30 s, find the magnitude, r, and direction, theta, of the bird's displacement during this time period. r = Number m theta = Number degree Now, assume the same bird is moving along again at 1.00 mph in an easterly direction but this time the...

04 Torce - (2.001 + 9.00J + J.JUK) N acts on a 2.90 kg object that moves in time interval 2.10 s from an initial posi- tion 7= (2.70i - 2.90j + 5.50k) m to a final position 72 = (-4.10i + 3.30j + 5.40k) m. Find (a) the work done on the object by the force in that time interval, (b) the average power due to the e Pare = 2 force during that time interval, and (c) the...

Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....

Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....

Chapter 07, Problem 009 Your answer is partially correct. Try again. The only force acting on a 1.3 kg canister that is moving in an xy plane has a magnitude of 4.5 N. The canister initially has a velocity of 2.3 m/s in the positive x direction, and some time later has a velocity of 4.0 m/s in the positive y direction. How much work is done on the canister by the 4.5 N force during this time? Number1035 Units...
