Answer:

The acceleration of the object is 20 meters per second square = 20 m/s^2

Explanation:

Recall that acceleration is defined as the change in velocity divided the time it takes for the change. Therefore , if the object accelerates from rest (zero velocity) to 70 m/s , the change in velocity is (70 m/s - 0 m/s = 70 m/s)

which divided by the 3.5 seconds it took for the change, gives:

acceleration = (70 m/s  /  3.5 s ) = 20  m/s^2

What do lenses do?
Dovator [93]
A convex lens makes light rays converge (come together) at the focal point or focus. The distance from the center of the lens to the focal point is the focal length of the lens. Convex lenses are used in things like telescopes and binoculars to bring distant light rays to a focus in your eyes.

A car traveling at 22.4 m/s skids to a stop in 2.25s. Determine the skidding distance of the car
vitfil [10]
\bold{Hello}


Given :

u = 22.4 m/s

v = 0

t = 2.25

s = ?



applying the equation of motion :


\bold{v = u + at}


putting the values , we get value of
\bold{a = 9.955 m/{s}^2}


putting value of a in other equation . :-


=> \bold{v^2 = u^2 + 2as}


by solving this , we get stopping distance :-


\bold{\large{s = 25.201 m}}






Hope It Helps You. ^_^
