The initial speed of a car moving with an acceleration of 2 m/s² is 5 m/s. What will be the final velocity of the car after 6 seconds?
17 m/s
12 m/s
10 m/s
7.5 m/s
- 3. Multiple Choice
A boat starts from rest with a velocity of v and moves with an acceleration of 10m/s². Calculate the distance covered by the boat in 5 seconds.
200 m
125 m
100 m
None of the above
- 4. Multiple Choice
If an object has an initial velocity u, final velocity v and time t. Which two equatons can be used to calculate the total distance covered by the object?
v = u+at S = ut + 1/2 at²
v = u+at v²− u²= 2aS
v²− u²= 2aS S = ut + 1/2 at²
Both first and second option is correct
