1) A net force of 75.5 N is applied horizontally to slide a 225 kg crate across the floor.
dimulka [17.4K]

Answer:

The acceleration of the crate is 0.3356\,\frac{m}{s^2}

Explanation:

Recall the formula that relates force,mass and acceleration from newton's second law;

F=m\,a

Then in our case, we know the force applied and we know the mass of the crate, so we can solve for the acceleration as shown below:

F=m\,a\\75.5\,N=225\,\,kg\,\,a\\a=\frac{75.5}{225} \,\frac{m}{s^2} \\a=0.3356\,\,\frac{m}{s^2}

Salem and Vernonville are 160 miles apart. A car leaves Salem traveling towards​ Vernonville, and another car leaves Vernonville
Paul [167]

Answer:

The speed of car leaves  Vernonville = 45 miles per hour

The speed of car leaves  Salem = 55 miles per hour

Explanation:

Given that distance between Salem and Vernonville = 160 miles

Lest take speed of car which leaves from Vernonville = V miles per hour

So the speed of car which leaves from Salem = V +10 miles per hour

These two car meet at time = 1 hr 36 min = 1.6 hr

Distance travel by car leaves from Salem = x

   x= (V+10) x 1.6    --------1

Distance travel by car leaves from Vernonville = 160 - x

  160 -  x= V x 1.6      ----------2

From equation 1 and 2

160 - (V+10) x 1.6  = V x 1.6

V= 45 miles per hour

So

The speed of car leaves  Vernonville = 45 miles per hour

The speed of car leaves  Salem = 55 miles per hour
