A car travelling initially at 7.0 m/s accelerates uniformly at the rate of +0.80m/s. What is its velocity after it accelerates for 125m?

C

Explanation:

Given;

Initial velocity, u = +7.0 m/s

accelerates, a = +0.80 m/s²

distance, s = 245 m

One of equation of motions is given by;

                                

where,

v is the final velocity in m/s

u is the initial velocity in m/s

a is the acceleration in m/s²

s is the distance in m

(a) The velocity of the car at end of the acceleration will be when it covers 245 m

                              

                              

                              

                              

                              

(b)  Velocity after the car accelerates for 125 m            

                            

                             

                             

                             

                             

(c)  Velocity after the car accelerates for 67 m                      

                             

                             

                             

                             

                             

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
