On an essentially frictionless, horizontal ice rink, a skater moving at 3.0 m/s encounters a rough patch that reduces her speed
JulsSmile [24]

Answer: 1.25 m

Explanation:

Given

initial velocity(v_i )=3 m/s

Final velocity(v_f)=0.55\times 3=1.65 m/s

Change in kinetic Energy =work done by Friction

change in Kinetic Energy=\frac{m}{2}\left ( v_i^2-v_f^2\right )

work done by friction=\mu mgL

\frac{m}{2}\left ( 3^2-1.65^2\right )=0.25\cdot mg\times L

3.135=0.25\times 9.8\times L

L=1.25

At the instant a traffic light turns green, a car starts with a constant acceleration of 1.3 m/s2. At the same instant a truck,
Bas_tet [7]

Answer:

(a) Distance traveled = 75.3846 m

(b) Velocity of car at that instant will be 14 m/sec

Explanation:

We have given acceleration of the car a=1.3m/sec^2

Initial velocity of the cart u = 0 m/sec

(a) According to second equation of motion we know that s=ut+\frac{1}{2}at^2

So distance traveled by car s_c=0\times t+\frac{1}{2}\times 1.3t^2=0.65t^2

As the truck is moving with constant speed

So distance traveled by truck s_t=ut=7t

As the truck overtakes the car

So s_c=s_t

0.65t^2=7t

t=10.769sec

So distance traveled s_c=s_t=7\times 10.769=75.3846m

(b) From second equation of motion we know that v = u+at

So v = 0+1.3×10.769 = 14 m /sec
