Question

write the equation of motion and do at least 10 numerical problem based on them​

Answer 1

Answer:

v = u + at

s = ut + (1/2)at²

v² - u² = 2as

Explanation:

write the equation of motion

u = initial velocity

v = final velocity

a = acceleration

t = time

s = distance

v = u + at

s = ut + (1/2)at²

s = (1/2)(u + v)t

s = vt - (1/2)at²

v² - u² = 2as

An object starts from rest with acceleartion of 1 m/s

Find velocity after 10 sec & distance covered

u = 0 m/s  ( at rest)

a = 1 m/s

t = 10 sec

v = u + at = 0 + 1*10 = 10 m/s

s = ut + (1/2)at² = 0 + (1/2)1*(10)² = 50 m

s = (1/2)(u + v)t = (1/2)(10)(10) = 50 m

s = vt - (1/2)at² = 10*10 - (1/2)1(10²) = 100 - 50 = 50 m

v² - u² = 2as => 10² - 0² = 2(1)s = > 100 = 2s => s = 50 m
