Can anyone solve this sum for me plzzz. A rocket with a lift-off mass ...
Mass of the rocket, m = 20,000 kg
Initial acceleration, a = 5 m/s
Acceleration due to gravity, g = 10 m/s
Using Newton’s second law of motion, the net force (thrust) acting on the rocket is given by the relation:
F – mg = ma
F = m ( g + a ) = 20000 × (10 + 5)
Hope it helps!!
Can anyone solve this sum for me plzzz. A rocket with a lift-off mass ...
Problem:
A rocket with a lift-off mass of 20,000 kg is blasted upwards with an initial acceleration of 5.0 m/s^2. Calculate the initial thrust (force) of the blast.
Solution:
To calculate the initial thrust (force) of the blast, we need to consider Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
Step 1: Identify the given values:
- Mass of the rocket (m) = 20,000 kg
- Initial acceleration (a) = 5.0 m/s^2
Step 2: Calculate the initial thrust (force):
Using the formula for force (F = m * a), where F is the force, m is the mass, and a is the acceleration, we can substitute the given values and solve for force.
F = m * a
F = 20,000 kg * 5.0 m/s^2
F = 100,000 kg·m/s^2
Therefore, the initial thrust (force) of the blast is 100,000 kg·m/s^2.
Explanation:
The initial thrust (force) of the blast is calculated using Newton's second law of motion. This law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. In this case, the mass of the rocket is given as 20,000 kg, and the initial acceleration is given as 5.0 m/s^2.
By substituting the given values into the formula F = m * a, we can calculate the force. Multiplying the mass (20,000 kg) by the acceleration (5.0 m/s^2) gives us a force of 100,000 kg·m/s^2.
This means that the initial thrust (force) exerted by the blast on the rocket is 100,000 kg·m/s^2.
