how far east? 73.04 how far north from starting point? 17 + 43.96 = 60.96km how far has the plan gone? x^2=73.04^2 + 17^2 = 74.99km

Ive done a drawing and to get the resultant vector, i need to draw a tail from the head of the second to the tail of the first and find that length. the length of this vector is the magnitude of the resultant vector. Should i paste in my picture?

do i have all the coordinates?

the plane went 73.04km. add the wind of 17. = 90.04

Homework Statement Plot on a graph the speed-time graph for the Mars lander (Fig 2.2) and find its regression line This should be y=3.7x+20 This tells you the initial speed was 20 m/s and the acceleration due to gravity on Mars is 3.7 m/s2 Homework Equations y=mx +...

simply put, 17+88?

cos theta = adjacent/ hypotenuse cos 37'=x/ 73.04 x=55.90584235 x=55.91km sin theta = opposite/hypotenuse sin 37'= y/73.04 y=73.04 sin 37 y=43.96km If the wind was blwoing from the south at 17km/hour, the wind is blowing due north. therefore: after 50 minutes at 17 km p/h, plane has...

you rock. tx!

50 minutes is 0.83 hours so now I have distance = speed x time distance = 0.83 x 88 73.04km I'm not sure what to use to get b and c - how far north and east? argh.

Homework Statement A plane is flying through the air at a velocity 88km/hr direction N37'E on a day when there is no wind. a) After 50 minutes, how far has the plane gone? b) How far east is it from it's starting point? c) How far north is it from its starting point? If there is a...

Thanks so much! I'm working so slowly trying to get it right. Thanks again, the feedback is a boost!

Homework Statement a boat heads north at 3.4 m s^-1 across a river that flows East at 1.6 m s ^-1. 1)Calculate the resultant velocity of the boat and the time taken to cross the river which is 180 m wide. 2)What is the distance traveled from its starting point when the boat reaches the...

Homework Statement A car accelerates from 0 to 30m s ^-1 in 5.0 seconds, travels at a constant 30m s^-1 for 15.0 seconds and then brakes to a stop in 10.0 seconds. 1) calculate the acceleration (assumed constant) in each section of the motion. 2) calculate distance travelled 3) what is...
