pls answer me hurryup​

Answer 1

Answer:

a. 200 m  

b. 4 m/s^2

Explanation:

a) Distance covered during acceleration = Area of the triangle on the left

                                                                    = 1/2 * height * base

                                                                    = 1/2 * 40 * 10

                                                                    = 200 m

b) Deceleration = (u-v)/t  = (40 - 0)/(20-10) = 40/10 = 4 m/s^2    

[u= initial velocity during deceleration, v = final velocity during deceleration, t= time interval of deceleration]

                         

Answer 2

Same thing as he wrote on top but he wrote faster
