6 sample questions

Question 1.
Calculate the final velocity of a car that starts from rest (u = 0 m/s) and accelerates at 2 m/s² for 4 seconds.
Show hintHide hint
Use the first equation of motion v = u + at.
Question 2.
If a runner has a constant acceleration of 1.5 m/s², how far will they travel in 10 seconds starting from rest?
Show hintHide hint
Substitute u = 0 since the runner starts from rest.
3Question 3.
What is the equation used to calculate final velocity?
- v = u + at
- v = ut + 1/2 at²
- v = 2as + u²
Show hintHide hint
This is the first equation of motion among the four.
4Question 4.
True or False: The equation s = ut + (1/2)at² includes the effect of acceleration.
- True
- False
Show hintHide hint
Think about what happens if acceleration is applied over time.
Question 5.
A car starts from rest and accelerates uniformly at 4 m/s². Calculate its velocity after 10 seconds and the distance traveled in that time.
Show hintHide hint
Use both the first and second equations of motion.
Question 6.
A ball is thrown straight up with an initial speed of 15 m/s, and it decelerates at 9.8 m/s² due to gravity. Calculate the maximum height it reaches.
Show hintHide hint
You will find the distance when you set final velocity to zero at the peak.
