Question

if any is moving with 50m/s speed and in 10 second it becomes 20m/s then acceleration



1) 1m/s square


2) 2m/s square

3) 3m/s square

4) - 3m/s square ​

Answer 1

Answer: 4) -3m/s square

Answer 2

Answer:

Here is your answer

Step-by-step explanation:

Given

Initial Velocity = 50 m/s

Final Velocity = 20 m/s

Time = 10 Seconds

Solution

Accelaration = (Final Velocity - Initial Velocity) / Time

Accelaration = (20 m/s - 50 m/s) / 10 Seconds

Accelaration = (-30 m/s) / 10 Seconds

Accelaration = -3 ms^-2

So, 4 option is the correct one
