Abus left austin at 6: 00 am and traveled to san antonio. after the passengers got off the bus, it returned to austin , arriving back at the terminal at 10: 30 am. what additional information is needed in order to determine the average speed of the bus?

The distance between cities

Explanation:

V= Distance/ Time

Time of round trip = 28.5 hours

Distance = X unknown

so

Vaverage = 2 x D / 28.5 hours = average speed

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
