Answer:
<h2>10.52 kg</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>10.52 kg</h3>
Hope this helps you
Answer:
180 meters
Explanation:
We know initial position and velocity of the dragster are both zero. We only know acceleration (43 m/s^2) and need to find out how far the dragster moves after 2.9 seconds.
x initial = 0
velocity initial = 0
t=2.9s
a= 43m/s^2
Plug into
180 meters or 1.8 x 10^2 meters is the answer accounting for 2 sig figs.
Answer:
The raduis of the geosynchronous orbit of the satellite around earth is 3.88×10^10m
Explanation:
The raduis of geosynchronous orbit of a satellite is given by:
R = Cuberoot(T^2GM)/4pi r^2
Given:
G = gravitational constant = 6.67×10^-11Nm^2
M = mass of earth = 5.98×10^24kg
r = radius of the earth = 6.38×10^6m
T = time period on the earth = 24hours
Changing hours to seconds = 24 ×60minutes ×60 seconds = 86,400seconds
Substituting into the equation
R = Cuberoot[ (86,400)^2 × (6.67×10^-11)×(5.98×10^24) / (4×3.142×(6.38×10^6)^2]
R = Cberoot [ (2.98×10^46)/(5.12×10^14)]
R = Cuberoot(5.82×10^31)
R = 3.88×10^10m
Answer:
The answer you asked would be
Explanation:
Gravitational potential energy is the energy stored in an object due to its position above the Earth’s surface.
This is due to the force of gravity acting on an object. Gravitational potential energy is calculated as follows:
Ep = m × g × h so a Gravitational potential energy is the energy stored in an object due to its position above the Earth’s surface. so the answer would be A ball with a mass of 500g is lifted onto a shelf which is 1.5m above the ground. Calculate the gravitational potential energy gained by the ball (g = 9.8 N/kg).
