A truck starting from rest, goes in a straight line to a velocity of 25 m/s in 12 s, find the acceleration of the truck

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

3cm and 6 and 9 cm that a possibility of that question
