Aluge run is straight for the first 10 m. if the velocity of the luger when he passes the start line is +25 m/s and his acceleration is constant at +9.5 m/s2, about how fast is he going when he hits the first turn? a. +14 m/s b. +26 m/s c. +29 m/s d. +225 m/s

Recall that

where is the luger's initial velocity, his final velocity, his acceleration, and the distance he traverses. Then

so the closest answer is C.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
