An object starts from 1 m / s and rises for 3 s with uniform acceleration a, and the velocity reaches 4 m / s (1) Acceleration a of uniform acceleration rise (2) Height of rise H

An object starts from 1 m / s and rises for 3 s with uniform acceleration a, and the velocity reaches 4 m / s (1) Acceleration a of uniform acceleration rise (2) Height of rise H

(1) 1 + 3A = 4 a = 1 direction up (2) H = VT + att / 2 = 7.5
