Explanation:
These brain chemicals, including adrenaline, dopamine and cortisol, stimulate a natural high and give you a boost of energy that makes you feel more alert, alive and able to scream your lungs out
The moon and the Earth attract each other, with equal gravitational forces.
That may not sound too surprising.
But what do you think of THIS one:
-- You and the Earth attract each other, with equal gravitational forces.
-- Your weight on Earth is the same as the Earth's weight on you.
Answer:
parabolic path
Explanation:
As the cart reaches the end of the table with a horizontally directed velocity (only horizontal component), the cart will follow a parabolic path given by the combined action of:
(1) kinematic equation for motion under constant velocity in the horizontal direction (linear expression in terms of time), and
(2) kinematic equation for motion under constant acceleration (that of gravity) in the vertical direction (quadratic expression in terms of time)
Answer:
1.4 m/s/s (2.s.f)
Explanation:
The formula for centripetal acceleration is:
, where v is velocity and r is the radius.
In the question we are given the information that the car has a mass of 1300kg, a velocity of 2.5m/s, and a turn radius of 8.5m which are all the values we need. Therefore we can simply substitute in the values to solve the question:
Therefore the centripetal acceleration of the car is 1.4m/s/s. (2.s.f)
Hope this helped!
