Answer:
12 m/s²
Step-by-step explanation:
mass of the car = 50 kg
The net force applied to the car is 800 - 200 = 600 N
Form the Newton's second law:
F = m*a
where F is the net force applied to the object, m is the mass of the object, and a is the acceleration of the object.
Then, the acceleration of the car (in m/s²) is:
a = F/m
a = 600/50
a = 12 m/s²
Answer:sei
49/12
Just mulitply the top and the bottom across.
7*7/4*3
72 hours
1hour30minutes times 48 cars (since TWO pass every 1:30, not one)
equals 72 hours, or three days
