Answer:
The acceleration of the crate is
Explanation:
Recall the formula that relates force,mass and acceleration from newton's second law;
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:
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
