Answer:
Answer is 20
Explanation:
As we know
\Large\boxed{ \tt{}F =ma}
F=ma
Here Given
★ F = 100
★ m = 25 kg
Putting in the equation
\leadsto\tt{100=25\times\:a}⇝100=25×a
On solving
\sf{\dashrightarrow\:a = 4 \:ms^{-2}}⇢a=4ms
−2
Now the body initially is stationary therefore initial velocity (u) must be zero
u = 0
Applying Newton 1st Law of Motion :
\sf\Large\boxed{ \tt{}v =u + at}
v=u+at
Substituting the values to find final velocity at t= 5 sec
\leadsto \tt{v = 0 + 4 \times \:5}⇝v=0+4×5
\tt{ \pink{\dashrightarrow\:v = 20 \:m/s}}⇢v=20m/s
☞ Hence, the final velocity is 20 m/s
