Question 2 Cars A and B are travelling in adjacent lanes along a straight road. At time, t = 0 their positions
and speeds are as shown in the diagram. If car A has a constant acceleration of 0.6 m/s2? and car
B has a constant deceleration of 0.46 m/s2, determine when A will overtake B.
(VA)o = 13 m/s?
А
(VB). = 20 m/s
B
*
30 m
Question 3
Position vs. time graph of a car is given below. Sketch a graph of velocity versus time and a
graph of acceleration versus time corresponding to the graph of displacement versus time given
in the graph.
A x (m)
t(s)​

You throw a baseball directly upward at time t = 0 at an initial speed of 12.3 m/s. what is the maximum height the ball reaches above where it leaves your hand? at what times does the ball pass through half the maximum height? ignore air resistance and take g = 9.80 m/s2.

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.
