A rubber block 1 cm x 3 cm x 10 cm is clamped at one end with its 10 cm side vertical. A horizontal subjec force of 30 N is applied to the free surface. What is the horizontal displacement of the top face? Bulk modulus of elasticity is 1.4×10³ Nm ².

which statement about this sum is true? −245+2.7

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

answer is slate

hope this
