Ex.3
mass 2 kg. Moving straight from a standstill with the acceleration constant 3 m / s2
when passing the landmark speed of 12 m / s
, while the speed is 24 m / s objects away from a landmark. m
How to
ask for help Distance from the observation point to the last point
= start to end - the beginning of a landmark
1. distance from beginning to end
S =? A = 3
T = U = 0 -
24 V = v2 = U2. + 2AS 242 = 02 + 2 (3) (s) = 0 + 576 6S s = 96 M 2. Find the distance from the starting point to the landmark S =? A = 3 T = U = 0 - 12 V =. U2 + 2AS v2 = 122 = 02 + 2 (3) (s) = 0 + 144 6S s = 24 M so far away from the landmark = 96-24 = 72 m.
