Question

a truck running along a straight road increases its speed uniformly from 15m/s to 30m/s time interval of 1 minute find the acceleration and distance travelled by the truck during this time interval

Answer 1

u=15m/s
v=30m/s
t=1minutes=60s
a=????(to be calculated)
$a = \frac{v - u}{t} = \frac{30 - 15}{60} = \frac{15}{60} = \frac{1}{4} = 0.25$
So, acceleration is 0.25m/s^2.
