Question

A car fell off a ledge and dropped to ground at 0.5s let g= 10m/s².find its average speed and height. Its urgent plzzz

Answer 1

Heya user !!!

Here's the answer you are looking for

Since the car fell off, it's initial velocity (u) = 0

Time taken (t) = 0.5s

Acceleration = g = 10m/s²

⏩Using the 1st equation,

v = u + at

v = 0 + (10)(0.5)

v = 5m/s

⏩Let height = s

Using the 3rd equation of motion,

v² - u² = 2as

5² - 0 = 2(10)(s)

25 = 20s

s = 25/20 = 1.25m

⏩ Average speed

= Total distance/total time

= 1.25/0.5 m/s

= 2.5m/s
