*A 1.8 kg block slides down a frictionless ramp, as shown in Figure 8-28. The top of the ramp is 1.5 m above the ground; the bottom of the ramp is h = 0.20 m above the ground. The block leaves the ramp moving horizontally, and lands a horizontal distance d away. Find the distance d.*

Now, I set the mechanical energy at the top of the ramp equal to the mechanical energy at the bottom of the ramp. Using that equation, I found the velocity of the block at the bottom of the ramp.

From there, I used kinematic equations to find the time it took for the box to fall, with a being g. Then, I used the time to find x. I kept on getting 1.1 m, but the answer is supposed to be 1.02 m. What am I doing wrong?? Thank you in advance!
