The space shuttle travels at 15,000 m/s in order to enter earth atmosphere it changes it's speed to 10,000 m/s over
100 seconds. What is the space shuttles acceleration?

Amplitude is a measure of a waves a; speed b; distance c; energy d; frequency

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f.s. = 2 against bucklin

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?
