· A ball is thrown vertically upwards with a velocity of 49m/s calculate maximum height and time taken to reach maximum height. H = U 2 /(2g) = (49 2)/(2 x )= m T = U/g = 49/ = 5 sec. A ball is thrown vertically upward with a velocity of 20 m/s. calculate maximum height and time taken to reach maximum height.
How to read an MTR/MTC – Step 1. The initial review of an MTR begins with a physical inspection of the material on the shop floor or in the warehouse. The heat number should be physically present and identifiable on the material's surface. This number is then compared with the associated MTR to ensure the two match.
