Hope this helps! Sorry no one answered your question sooner :(
Answer:
Warm front
Explanation:
A warm front is the transition zone of the replacement of a cold air mass by a warm air mass. The pressure centers of warm fronts are usually low and the pressure read by a barometer will decrease due to an incoming warm front
The general direction of motion of warm fronts is from southwest to northeast with warmer and moist air behind the warm front than air into which the front flows. Therefore, warm fronts normally results in moderate precipitation or rainfall or snow.
Force required = F = ?
mass of the car = m = 1200 kg
initial velocity of the car = Vi = 10 m/sec
final velocity of the car = 0
time required to stop the car = t = 20 sec
Using Newton`s 2nd law of motion;
F = ma ………………………(1)
as a = Vf - Vi / t , put this value in equation (1)
F = m ( Vf - Vi /t ) ………………(2)
F = 1200 ( 0 - 10 /20) = - 600 N
here Negative sign shows that external force is acting in opposite direction of the motion to bring it to rest.
we can also calculate this force by using the relation
Rate of change of momentum = net force acting on the object …………(3)
m Vf - m Vi / t = net force acting on the object
m (Vf - Vi / t) = F
1200 ( 0 - 10 /20) = - 600 N = F
so, net force acting on the object =F = - 600 N
