Sorry I meant I’m getting an angle of 45 when I draw my diagram not the actual angle that needs to be solved for using sine. When I add 15 and 30 based on my diagram I get 45. Is that the right angle to plug into the cosine law?
An airplane has an air velocity of 500 km/h [N 30 E] and encounters a wind from [S 75 W] at 180 km/h, find the ground velocity. Make sure you draw a big, labelled diagram.
Please help! I’m understand the calculations that need to be done (cosine law then sine law for the angle) but I’m a little...
Yes the velocity was not specified in the question, it was more so a scenario to think about. The reason I chose 0.5 as my answer is because I thought that the velocity of the small mass Ball B would change more; in the sense that the smaller mass would lose some energy to the bigger mass...
I'm a little confused as to what the answer could be. This was one of my homework questions that I got wrong as I chose 0.5 v as the answer. Would someone be able to tell me what the correct answer would be?
Thank you for replying, but when solving I didn't drop the masses I just substituted 11 + v1f = v2f into this equation m1v1+m2v2 = m1v1f + m2v2f after inputting the values.
A 0.045 kg golf ball is hit by a driver. The head of the driver has a mass of 0.15 kg, and travels at a speed of 56 m/s before the collision. The ball has a speed of 67 m/s as it leaves the clubface. What is the speed of the head of the driver immediately after the collision?
I'm not sure...
