Question

Question 2 (1 point) [OLMPC1] The Canadian Bobsled team produces the following data for a warm up run in the Olympics: a. Graph the corresponding velocity-time graph b. Graph the corresponding acceleration-time graph c. Determine their total displacement 500.0 400.0 300.0 200.0 (El) P 100.0 0 0 2.0 4.0 8.0 10.0 6.0 t(s)

Answer 1

* Assume given graph as s-t graph.

* By calculating velocity and accelaration we can draw v-t and a-t graphs

a) From the given graph we can calculate velocity at t= 0,2,4,6.8.10 sec.

By assuming given graphn as displacement - time (s-t) graph.

From the given s-t graph velocity at diferent time can be calculated using this formula V = S / t

t (s) V (unit/s)

0 undefined

1 400

2 150

   4 50

6 17

8 1.25

10 0

when t=0 bobsled desn't start , then velocity undeined.

b)   From the v-t gaph we can calculate accelaation at t= 0,2,4,6.8.10 sec.

   From the given v-t graph accelaration at different time can be calculated using this formula a = V / t .

t (s) a (unit /s² )

0 undefined

1 400

2 75

4 12.5

6 3

8   0.2

10 0

   when t=0 bobsled desn't start , then no possibility of accelaration.

c)   To calculate total displacement we should consider s-t graph

From the s-t graph total displacement s=400 unit

No displacement is possible when t=0.
