Two objects, mi and m2 are connected by a light string. The object of m= 4 kg lies on a rough horizontal surface while the second object me = 6 kg is suspended in air
Both objects start to accelerate when released from rest in the direction as shown in
Figure 2. Determine the tension in the string.

True or false graphs must include scales that increase by the same amount

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
