A car accelerates from rest for 8.0 s, and reaches a speed of 66 m/s. How far will the car travel?
a) 8448 m
b) 2112 m
c) 264 m
d) 528 m

C

Explanation:

Find the acceleration using this kinematic equation:

Now use this kinematic equation to find the displacement:

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
