A cart changes its speed from rest to 100 m/s in 1 s. During this interval its acceleration is

Expert Solution

Solution :-

Given :-

Speed – 100 m/s

Time – 1 s

Then calculate acceleration ,

Therefore the formula for acceleration is given by

Acceleration = Velocity / time

And unit of the acceleration is m/s²

But , in this problem the given value is speed and time so in conceptually the formula for acceleration is

acceleration = Speed / time

unit of speed is – meter/second (m/s) & unit of time is second (s)

Now calculate acceleration by using formula and given value ,

A = s / t

t = time

S = speed

A = acceleration

A = (100)m/s / 1 s

A = 100 m/s²

The acceleration is 100 m/s²

1. A particle starts from rest, increasing its speed evenly, traveling a distance of 10.0 (m) in a time of 1.40 (s). From that moment it is kept at constant speed for 1.00 (s). Then its speed decreases to rest in a time of 2.80 (s). Calculate the total displacement of the particle. STEP BY STEP PLEASE
