5. a cyclist is traveling along a level, straight road at 10 m/s in the positive direction with a x; = v. in
magnitude of the velocity for the cyclist is tracked using the following motion graph.
velocity-time graph
velocity (m/s)
0 1 2 3 4 5
time (s)
according to the information and graph shown above, what is the magnitude of the acceleration for the first
two seconds?
a. 2 m/s2 ~
c. 12 m/s2
b. 24 m/s2
d. 1 m/s2

Ineed ! using proper grammar, spelling, and punctuation, write at least one 5 sentence paragraph describing 3 ways we use the elements of the electromagnetic spectrum (ems) in our everyday lives.

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
