1) Apply the rule for significant figures and solve for problems la through ac a) Compute the value for A A = 0.5 xh( a + b ); a = 2.54 m; h = 5.64 m; b = 3.00 m -0.5.(5.64 ) (2.54 +3:00) = 15.6228 A=15. lem Calculate A = TX; - 3.142 ; r = 5.0 m = 3,142 x (5.0) -78.55 Calculate A=79 V = 0.33x nh(r? + R² + R); T = 3.142; h = 6.3 m; r = 2.5m ; R = 5.07 m : 0.33X (3.142) (6.3) (0.52 + 5.072+ (2.5815.07)) = 291.5 - 0.33.119.7946) (6.25+25.705 +12,67515 B - 4.53248 275 4.13 - 291.532 125 km a.hr 80 km 80-25=55 2) V=292 A motor cyclist practising on a rectangular course begins his run from location A shown in the diagram above. He rides to the corner B and then all the way to end C. He turns towards point D but runs out of fuel 25 km away from D. The total time up to that point was 2.5 hours. a) Calculate the average speed of the motorist up to where he ran out of fuel. Hverage speed a total distance 410 time time 2.5 temo b) Calculate his average velocity at that time. Vay = 1/2( HD -D= ao
