What is the speed of an object after falling (from rest) a distance of 9.80 meters near the surface of the Earth? Assume air
madam [21]

Hi there!

We can use the kinematic equation:

v_f^2 = v_i^2 + 2ad

vf = Final velocity (? m/s)

vi = initial velocity (0 m/s, dropped from rest)

a = acceleration (due to gravity, 9.8 m/s²)

d = distance (9.8 m)

Simplify the equation to solve for vf:

v_f^2 = 0 + 2ad\\\\v_f = \sqrt{2ad}

Substitute in the given values:

v_f = \sqrt{2(9.8)(9.8)} = \boxed{13.86 m/s}

What is stopping distance of a body at 20 m/s is decelerated at 2m/s² to rest?<br>​
AlladinOne [14]

Answer:

s = 100 m

Explanation:

v² = u² + 2as

s = (v² - u²) / 2a

s = (0² - 20²) / 2(-2)

s = 100 m

if the displacement of a car was 150 km [E] and the velocity was 15.0 km/h [E], what was the travel time?
soldi70 [24.7K]
Given,
Displacement of the car = 150 km
Velocity of the car = 15.0 km/h

We need to calculate the travel time t

We all know that the formula to calculate velocity is

Velocity = displacement / time

From the above equation,

Time = Displacement / Velocity

Substituting the values in the above equation, 

Time = 150 / 15.0 = 10 hours
Therefore, travel time = 10 hours.
