A distance/time graph is drawn to represent a trip John took by car to Edmonton. The time is given in hours and the distance in kilometers. Two points on the graph are (2, 50) and (5, 320). What was John's average velocity between these points?
Select one:
a. 80 km/h
b. 90 km/h
c. 100 km/h
d. 110 km/h

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
