Question

question 1 - 1
the same force was applied to four different toy cars. the mass of each car was recorded in the data table below
based on the data in the table, which car had the lowest acceleration?
car a
car b
car c
car d

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\), where \(F\) is force, \(m\) is mass, and \(a\) is acceleration. We can solve for \(a\) as \(a=\frac{F}{m}\).

Step2: Calculate acceleration for each car

• For Car A: \(a_A=\frac{3}{2.0}=1.5\space m/s^{2}\)
• For Car B: \(a_B=\frac{3}{0.5}=6\space m/s^{2}\)
• For Car C: \(a_C=\frac{3}{4.0}=0.75\space m/s^{2}\)
• For Car D: \(a_D=\frac{3}{1.5}=2\space m/s^{2}\)

Answer:

Car C
