How would i set these up? like what is the equations?
# A tennis player hits a tennis ball with a force of 330 N, and it accelerates at the rate of 5,500 m/s2. What is the mass of the tennis ball?
# Li is pedaling his bike with a force of 220 N. The combined mass of Reese and her bike is 55 kg. What is the acceleration of his bike?
To solve the first problem, you can use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration. The equation for this law is:
Force = mass * acceleration
In this case, the given force is 330 N, and the given acceleration is 5,500 m/s^2. We need to find the mass of the tennis ball.
So, the equation becomes:
330 N = mass * 5,500 m/s^2
To find the mass, you can rearrange the equation to solve for mass:
mass = 330 N / 5,500 m/s^2
Now you can calculate the mass by dividing the given force by the given acceleration.
To solve the second problem, again, you can use Newton's second law of motion. The given force is 220 N, and the combined mass of Reese and her bike is 55 kg. We need to find the acceleration of the bike.
Using the equation for Newton's second law:
Force = mass * acceleration
Rearranging the equation to solve for acceleration:
acceleration = Force / mass
Substituting the given values:
acceleration = 220 N / 55 kg
Simply divide the given force by the given mass to find the acceleration.
