Question

an object with an initial speed of 4.0 meters per second accelerates uniformly at 2.0 meters per second˛ in the direction of its motion for a time of 5.0 seconds. what is the final speed of the object?

Answer 1

6m/s

Step-by-step explanation:

Key

Vi = 4.0 m/s

A = 2.0 m/s/s

D = 5.0 m

Vf = X or ??

Vf =Vi+2ad

Vf =(4m/s)+ 2(2m/s)(5m)

Vf =16(m/s)+ 20(m/s)

Vf =36(m/s)

Vf =6m/s
