GIVEN
A 3 kg model airplane is traveling at a speed of 33 m/s. The operator then increases the speed up to 45 m/s in 2 seconds.
TO FIND
How much force did the engine need in order to make this change?
SOLUTION
The above problem can be simply solved as follows;
Force = Mass × acceleration
Acceleration(a) = (final velocity - initial velocity)/Time
= (45-33)/2
= 12/2
= 6m/s²
Force = 3 × 6
= 18 N
Hence, The answer is 18N
