(b) Fig. 3.2 shows the speed and direction of motion of an object at a point in time, 150.0 m/s
object
Fig. 3.2
The resultant force on the object is zero for 10 seconds.
Deduce the speed and direction of motion after 5 seconds. Indicate the speed and direction
of the object by drawing a labelled arrow next to the object in Fig. 3.3.

How many neutrons does element x if it’s atomic number is 28 and its mass number is 87

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
