Answer:
The velocity of the block is 22 m/s.
Explanation:
Given that,
Mass = 2.50 kg
Velocity = 8 .00 m/s
Force = 7.00 N
Time t = 5.00
We need to calculate the change in velocity it means acceleration
Using newton's law
[tex]F = ma[/tex]
Where,
m = mass
a = acceleration
Put the value into the formula
[tex]a=\dfrac{F}{m}[/tex]
[tex]a = \dfrac{7.00}{2.50}[/tex]
[tex]a= 2.8m/s^2[/tex]
We need to calculate the velocity of the block
Using equation of motion
[tex]v = u+at[/tex]
Where,
v = final velocity
u = initial velocity
a = acceleration
t =time
Put the value in the equation
[tex]v= 8.00+2.8\times5.00[/tex]
[tex]v=22\ m/s[/tex]
Hence, The velocity of the block is 22 m/s.
