Explanation:
The centripetal acceleration is given as
The velocity of the car can be calculated using the circumference of the track and the period of the car.
So, the acceleration is
Answer:
No she cannot.
Explanation:
Let be the horizontal component of the ball velocity when it's kicked, assume no air resistance, this is a constant. Also let
be the vertical component of the ball velocity, which is affected by gravity after it's kicked.
The time it takes to travel 95m accross the field is
or
t is also the time it takes to travel up, and the fall down to the ground, which ultimately stops the motion. So the vertical displacement after time t is 0
where g = -9.8m/s2 in the opposite direction with
Since the total velocity that the goal keeper can give the ball is 30m/s
Let substitute x = > 0
We can multiply both sides by x
As
The solution for this quadratic equation is indefinite
So it's not possible for the goal keeper to do this.
Answer:2 m right
Explanation:
Given
First child is sitting 1 m left from Pivot point
Mass of second child is half of first
Let mass of first child be m
Second child
In order to balance see saw torque must be zero about pivot
x=2 m right from pivot point
