+28 A man pulling an empty wagon causes it to accelerate at 1.4 m/s2.
Part A
What will the acceleration be if he pulls with the same force when the wagon contains a child whose mass is three times that of the wagon?
Express your answer using two significant figures.
a = ______________ m/s2
+14985 Hello dish, good morning!
man pulling an empty wagon causes it to accelerate at a1 = 1.4 m/s2.
Part A
What will the acceleration (a2) be if he pulls with the same force when the wagon contains a child whose mass is three times that of the wagon?
Express your answer using two significant figures.
a = ______________ m/s2
\(F=m1\times a1=m2 \times a2\)
\(a1= 1.4 \frac {m}{s^2}\)
\(a2=\frac {m1}{m2} \times a1\)
\(a2=\frac {m1}{m1 \times 4} \times a1\)
\(a2=\frac {a1}{4}\)
\(a2=\frac {1.4 \frac {m}{s^2}}{4}\)
\({\color{blue}a2=0.35 \frac {m}{s^2}}\)
\(The \ stroller \ accelerated \ with \ {\color{blue}a2=0.35 \frac {m}{s^2}}\)
