Question

Calculate the acceleration and distance traveled before it stops. plsssssssssss answer fast first to answer will be marked brainliest

Answer 1

Explanation:

Distance is basically the area under (v-t) curve ..so here uu have to take area of triangle for distance

and for accelaration use 1st eq'n motion ..i.e. at t=0 , u=40m/s and at t=10sec , v=0

v = u + at

0 = 40 + a(10)

-40 = a(10)

a = -4m/sec^2

negative sign shows that the object is not accelarating , it is deaccelarate at the rate of (4m/s per sec)...

hope it helps you....
