A car is stationary at first it moves off with an acceleration of 2m.s Calculate how fast it will be moving after 10s
a = 2
v = 2t + c , where c is a constant and t is in seconds
when t = 0 , v = 0
0 = 0(t) + c ----> c = 0
so v = 2t
after 10 s, v = 2(10) or 20 m/s
Luhlaza high school is your school SUBJECT? That must be very interesting.
To calculate the final speed of the car after 10 seconds, we need to use the kinematic equation:
v = u + at
Where:
v is the final velocity (the speed we want to find),
u is the initial velocity (which is zero, as the car is stationary),
a is the acceleration (which is 2 m/s^2),
t is the time (which is 10 seconds).
Plugging the values into the equation:
v = 0 + (2 m/s^2) * 10 s
v = 0 + 20 m/s
v = 20 m/s
Therefore, the car will be moving at a speed of 20 m/s after 10 seconds.
