Question #349145

What is the horizontal force needed to accelerate a 42 kg grocery cart from rest to a velocity of 0.80 m s in 1.75 s

Expert's answer

Given:

"m=42\\:\\rm kg"

"v_1=0\\:\\rm m\/s"

"v_2=0.80\\:\\rm m\/s"

"t=1.75\\:\\rm s"

"F=ma=m\\frac{v_2-v_1}{t}"

"F=42*\\frac{0.80-0}{1.75}=19.2\\:\\rm N"
