Answer 1

Explanation:

A body is moving vertically upwards. Its

velocity changes at a constant rate from 50 m s' to

20 m s' in 3 s. What is its acceleration

?ANSWER

Acceleration, a=

Time

FinalVelocity−InitialVelocity

=

3s

20m/s−50m/s

=−10m/s

please follow me I will give your answer on time it's my promise to you

Answer 2

Answer:

-10m/ssquare

Explanation:

acceleration is equals to

$v - u \div t$

V=20m/s,U=50m/s,T=3sec

So, a=20-50 divide by 3 .that is equals to -30divide by 3 .= -10 m/s square
