Answer:
Acceleration, a = 2.38m/s²
Explanation:
Given the following data;
Mass = 1.01 kg
Force = 2.4N
To find the acceleration;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
- F represents force.
- m represents the mass of an object.
- a represents acceleration.
Making acceleration (a) the subject, we have;
Substituting into the equation, we have;
<em>Acceleration, a = 2.38m/s²</em>
<em>Therefore, the magnitude of the acceleration of the ball at the time of the crash is 2.38 meters per seconds square. </em>
Answer:
Explanation:
Let the ball is thrown upwards with speed u and reaches upto height h.
Use III equation of motion
here, final velocity v = 0
So,
Now as the ball reaches the maximum height, it starts falling freely. Let it strkes with the ground with velocity v'.
here, u = 0
So,
It means the velocity is same as the velocity of projection.
