Question
A car initially at rest accelerates linearly at a constant rate for eight seconds. If the total displacement of the car was 600 m, what was the speed of the car after the eight seconds of acceleration?(A) 50 m/s(B) 100 m/s(C) 150 m/s(D) 200 m/s
Step 1
We can use the first equation of motion to find the final speed (v) of the car. The first equation of motion is: \[v = u + at\] where a is the acceleration. Since u is 0, the equation simplifies to: \[v = at\] Show more…

A car initially at rest accelerates linearly at a constant rate for 5 s. If the final speed of the car is 15 m/s, what was the acceleration of the car? (A) 50 $\mathrm{m}$ (B) 100 $\mathrm{m}$ (C) 150 $\mathrm{m}$ (D) 200 $\mathrm{m}$
Practice Test 4
Section 1
A car starts from rest and accelerates at a constant rate over a time of 5.00 s for a distance of 100.0 m. Determine the acceleration of the car. a) 2.00 m/s2 b) 8.00 m/s2 c) 20.0 m/s2 d) 4.00 m/s2
A car moving with constant acceleration covered the distance between two points $60.0 \mathrm{~m}$ apart in $6.00 \mathrm{~s}$. Its speed as it passed the second point was $15.0 \mathrm{~m} / \mathrm{s}$. (a) What was the speed at the first point? (b) What was the magnitude of the acceleration? (c) At what prior distance from the first point was the car at rest? (d) Graph $x$ versus $t$ and $v$ versus $t$ for the car, from rest $(t=0)$.
