Ok - thank you. But, to find the x and y components don't I need to know the angles that go with each distance? How do I find the angle for 4 m East? or .50 m North? Thats mainly what I got stuck on. =].
Homework Statement
A golfer, putting on a green, requires three strokes to "hole the ball." During the first putt, the ball rolls 4.0 m due east. For the second putt, the ball travels 3.0 m at an angle 20° north of east. The third putt is 0.50 m due north. What displacement (magnitude and...
the work I did was:
Vo = 0 m/s
d = 2.8 km (or 2800 m)
V = 30 m/s
d=.5(Vo+V)t
2800 = .5 (0 + 30) t
t = 186.67 seconds
d= Vo + .5 at^2
2800 = 0 + .5 (186.67)^2a
a = .161 m/s^2
A car is traveling at a constant speed of 30 m/s on a highway. At the instant this car passes an entrance ramp, a second car enters the highway from the ramp. The second car starts from rest and has a constant acceleration. What acceleration must it maintain, so that the two cars meet for the...
Two motorcycles are traveling due east with different velocities. However, four seconds later, they have the same velocity. During this four-second interval, motorcycle A has an average acceleration of 1.6 m/s2 due east, while motorcycle B has an average acceleration of 3.6 m/s2 due east. By how...
