Answer to Question #117309 in Mechanics | Relativity for irish

Question

An airplane flying 60 m/s is accelerated uniformly at the rate of 0.5 . What is the velocity at the end 10 s

Answer 1

Solution.

$v_0=60m/s;$

$a=0.5 m/s^2;$

$t=10s;$

$v-?;$

Acceleration at uniformly accelerated motion is determined by the formula:

$a=\dfrac{v-v_0}{t};\implies v=v_0+at;$

$v=60m/s+0.5m/s^2\sdot10s=65m/s;$

Answer: $v=65m/s.$
