2. ### How much time is needed for a car to accelerate from 8.4 m/s to a speed of 16 m/s if the acceleration is 2.4?

V=u+at [v-final velocity u-initial velocity a-acceleration t-time] v=u+at v-u=at 16-8.4=2.4t 2.4t=7.6 t=7.6/2.4 t=3.17

3. ### How much time is needed for a car to accelerate from 4.3 m/s to a speed of 27 m/s if the acceleration is 4.3 m?

V(t)=Vo+at = 27=4.3+4.3*t So t = [27-4.3]/4.3 = 5.3s

8. ### Why do we need lazer beam to measure light speed, why don't we use for example reflected light from mars surface?

For measuring any speed, you need time and distance. The distance from here to Mars is in a constant state of flux; what value to use? With a laser, the distance can easily be held constant.

9. ### What angular speed (in revolutions/second) is needed for a centrifuge to produce...?

Hello Emile, let us use the relation acceleration (centrifuge) = r w^2 So w^2 = a / r = 1000 g/r g = 9.8 and r = 0.15 m Plugging and solving we get, w^2 = 65333 So w (angular frequency) = 255.6 rad/s 2 pi radian = 1 revolution So 255.6 rad = 41 (nearly) revolution...
