Question

Find the angle between the following two vectors using the scalar product method Town D is directly 10 km west of town a If a traveler walks 5 km at 30 deg towards north of west to town B. then turm south at a 90 deg angle to the vector AB The traveler proceeds 5 km at this bearing to town C. Calculate the distance of town D from C. Calculate the angle that the traveler has to turn to go to D. A pole-vault player clears a hurdle and drops to the floor. If the takes 0.5 sec to drop through the middle 1/3 of the height, find the total height The point guard in a basketball game shoots a last second shot from a distance of 21.6 m (71 ft) and makes the basket The basket height was 3 m (10 ft) and the ball was released at a height of 2 5 m and at angle of 45 degree. Find the initial velocity of the ball During an Apollo launch, the first wage fired its engines for 168 seconds and at engine cutoff, the vehicle was at an altitude of about 61.000 in f 200.000 feet (61 km), and was moving about 7,700 feet per second ( 2.300 m/s). Find the average acceleration of the rocket Calculate the distance traveled by the rocket with the average acceleration. How do you explain the discrepancy between then 61 km altitude and your answer? Using these distance found in the and the given altitude find an average angle of direction of the rocket's path. Find the maximum height the first r stage would reach if it was ejected at
