The tram

The tram is moving with acceleration a = 0.3m/s2. How long it will pass the first meter of track? How long does it take 10 meters. What is its speed at the end of the 10 meters track?

Result

t1 =  2.582 s
t2 =  8.165 s
v2 =  2.45 m/s

Solution:

a=0.3 s1=1 t1=2 s1/a=2 1/0.32.582=2.582  s a = 0.3 \ \\ s_{ 1 } = 1 \ \\ t_{ 1 } = \sqrt{ 2 \cdot \ s_{ 1 }/a } = \sqrt{ 2 \cdot \ 1/0.3 } \doteq 2.582 = 2.582 \ \text{ s }
s2=10 t2=2 s2/a=2 10/0.38.165=8.165  s s_{ 2 } = 10 \ \\ t_{ 2 } = \sqrt{ 2 \cdot \ s_{ 2 }/a } = \sqrt{ 2 \cdot \ 10/0.3 } \doteq 8.165 = 8.165 \ \text{ s }
v2=a t2=0.3 8.165=2.4495=2.45  m/s v_{ 2 } = a \cdot \ t_{ 2 } = 0.3 \cdot \ 8.165 = 2.4495 = 2.45 \ \text{ m/s }



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
