Question

mojo cycle changes
changes its velocity from 36 kmph
to 90kmph when its mass is 800 kg
Find work​

Answer 1

Answer:

GIVEN :-

u = 36km/h = 10 m/s

v = 90km/h = 25 m/s

m = 800kg

a = 10 m/s²

W.K.T - W =  F × S

BY 3rd equation of motion

∴2aS = v² - u²

∴ 2 × 10 × S = (25)² - (10)²

∴ 20S = 625 - 100

∴ S = 525÷20

∴ S = 26.25m

so by this

W = F × S

W = m×a×s

W = 800×10×26.25

W = 2,10,000 JOULE

Step-by-step explanation:

SO WORK IS 210000J
