Please Hurry!!! 25 Points A van increased in speed from 20 km/hr to 30 km/hr in 5 seconds. A truck increased in
speed from 40 km/hr to 60 km/hr in 15 seconds. Calculate the acceleration of each. Include
units.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

What is a good example of instantaneous speed

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.
