Answer:
0.381 m
Explanation:
Distance traveled S is found by
Where S is distance traveled, u is initial velocity, t is time, a is acceleration
Since we acceleration a is given as 60g, where g is gravitational constant of 9.81 then a=60*9.81=588.6
The initial velocity u is zero hence ut=0
Substituting a with 588.6, t with 36 ms
S=0.381 m
The object shown is a convex mirror. A convex mirror has a reflective surface and the body of it is curved outwards, it is used in sunglasses, security areas, telescopes, and magnifying glass.
Mass of yellow train, my = 100 kg
Initial Velocity of yellow train, = 8 m/s
mass of orange train = 200 kg
Initial Velocity of orange train = -1 m/s (since it moves opposite direction to the yellow train, we will put negative to show the opposite direction)
To calculate the initial momentum of both trains, we will use the principle of conservation of momentum which
The sum of initial momentum = the sum of final momentum
Since the question only wants the sum of initial momentum,
(100)(8) + (200)(-1) = 600 m/s
