a boat travels at 2.0m/s east towards a port , 2.2km away . when the boat reaches the port the passengers travel in a car due north for 15minutes at 60 km/h calculate the average speed in m/s​

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

this would be about 43%

total distance/total time

(85 + 82)/(5+3)

167/8
