A rubber ball weighs 95 N
a. what is the mass of the ball ?
b.what is the acceleration of the ball if an upward force of 69N is applied
a. W = m g, so m = W/g
Divide the weight (in Newtons)by the acceleration of gravity (9.8 m/s^2) and you will get the mass in kilograms
b. F = ma, so a = F/m
Use the m from part (a)
The answer will depend upon whether the 69 N "applied" force F includes the weight. If it doesn't, the ball will still fall downwards, in reposnse to a net force of 69 -95 = -26 N
To find the mass of the ball, we can use Newton's second law of motion, which states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a). Mathematically, it can be expressed as:
F = m * a
a. To find the mass (m) of the ball:
Step 1: Use the given weight of the ball, which is 95 N, as the force (F) acting on the ball.
Step 2: Rearrange the formula to solve for mass (m) by dividing both sides of the equation by acceleration (a).
m = F / a
Since no acceleration value is provided for this question, we cannot calculate the mass of the ball without additional information.
b. To find the acceleration (a) of the ball:
Step 1: Use the given upward force of 69 N as the force (F) acting on the ball.
Step 2: Rearrange the formula to solve for acceleration (a) by dividing both sides of the equation by the mass (m).
a = F / m
Again, since no mass value is provided for this question, we cannot calculate the acceleration of the ball without additional information.
