Acar accelerates for 5 seconds at 2.1 m/s squared if the car initially had a speed of 10 m/s what is its new speed?

Note that velocity is measured in meters per second (m/s) and acceleration is in meters per second squared ()

Our initial velocity is 10 m/s and then the car accelerated for 5 seconds at 2.1 \\

Note that

So our final velocity is our initial velocity + a*t;

i think the answer would be b

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
