Q1: A car's displacement is represented by the equation: x=1+5

Find

a) The car's displacement at t=2 s and, =5s

b) The average velocity of the car

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
