Question

a car occupies a velocity of 72 km per hour in 10 seconds starting from rest find acceleration velocity and distance​

Answer 1

Answer:

a car acceleration is 1km/hr and velocity is 10km/hr and distance is 50 km

Answer 2

Answer:

Initial Velocity = u = 0

Final velocity = v = 72 km/hr = 72 x 5/18 = 20 m/s

Time = t = 10 sec

Acceleration = a

Equation of motion :-

v = u + at

20 = 0 + 10a

a = 20/10

a = 2 m/s²

displacement = distance traveled = s

Equation of motion :-

v² - u² = 2as

20² = 2 × 2 × s

400 = 4s

s = 400/4

s = 100 m

Average velocity = displacement / time

= 100 / 10

= 10 m/s

Hope this helps you !
