If a truck starts from rest and it has acceleration of 4 m/s for 5 second calculate its final velocity. What will be the distance travelled by the truck during the time interval? ​

Respuesta :

Answer:

20m/s final velocity, 60meters is the distance

Explanation:

since it accelerates 4m/s we can assume every second it goes up by 4 so we do 5×4=20...

while for the distance we have to think about the fact that every second the speed changes (precisely every second adding 4m/s) so in the first second its going to travel 4 meters in the second 8m in the third 12m in the fourth 16m and in the fifth 20m... so we just calculate them for addition and get 60 meters
