Answer:

v= 0.89 \frac{m}{s}

Explanation:

Momentum zero:

m_{p}* v_{p} +m_{b}* v_{1} + m_{b1}* v_{1} = 0

Replacing

5.3 kg *10 \frac{m}{s} + v_{1} * ( 35kg + 24 kg) =0\\ 53 + v_{1}* 59=0\\v_{1} =-\frac{53}{59} = -0.89 \frac{m}{s}

If I exert a 203 N force on a 58 kg box, what will the acceleration of the box be?
Anit [1.1K]

Answer:

<h2>3.5 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

m is the mass

f is the force

From the question we have

a =  \frac{203}{58} =  \frac{7}{2}   \\

We have the final answer as

<h3>3.5 m/s²</h3>

Hope this helps you
