Hey There!
According to science, if the same forces are applied, than the door will not move due to similar strength. So, regardless the door won't move.
Have A Brainly Day!
<span>Breaking down is an emergency situation.
If your vehicle breaks down pull off the roadway, and if possible, park so that your vehicle can be seen for 200 feet in each direction.You should also m</span>ove the vehicle so all four wheels are off the pavement and turn on the emergency flashers. If there are other passengers in the car they should all get out <span>on the side away from traffic.</span>
Answer:
1.68 s
Explanation:
From newton's equation of motion,
a = (v-u)/t.................................. Equation 1
Making t the subject of the equation
t =(v-u)g............................. Equation 2
Where t = time taken for the bowling pin to reach the maximum height, v = final velocity bowling pin, u = initial velocity of the bowling pin, g = acceleration due to gravity.
Note: Taking upward to be negative and down ward to be positive,
Given: v = 0 m/s ( at the maximum height), u = 8.20 m/s, g = -9.8 m/s²
t = (0-8.20)/-9.8
t = -8.20/-9.8
t = 0.84 s.
But,
T = 2t
Where T = time taken for the bowling pin to return to the juggler's hand.
T = 2(0.84)
T = 1.68 s.
T = 1.68 s
