AI Thread Summary
To calculate the average velocity of a thunderstorm, one must determine both the direction and magnitude of its movement. The storm's initial position was 55 miles northeast, and by 11:00 PM, it had moved to 80 miles north. A diagram can aid in visualizing the storm's path and calculating the angle for direction. The average velocity can be computed using the definition of average velocity, which involves the change in position over time. Following a systematic approach and relevant equations will yield the correct answers for both direction and magnitude.

can anybody answer this physics question?

A meteorologist tracks the movement of a thunderstorm with Doppler radar. At 8:00 PM, the storm was 55 miles northeast of her station. At 11:00 PM, the storm is at 80 miles north.
a) What is the direction of the average velocity of the storm? _______________°north of west
b) What is the magnitude of the average velocity of the storm? ______________ miles/hr

Time do draw a diagram again - and a reasonably accurate one - a scale diagram even, using a protractor and ruler.
 


Welcome to PF p5oct!

Please be sure to follow the rules for homework help threads (you will receive a private message with more information). The template provided is a very useful and systematic approach for solving problems. For instance, it asks you to list the relevant equations: for instance what is the definition of average velocity? So, based on that, and the info that have been given, how would you compute it?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
