If an object has acceleration of zero meters per second², then the object is traveling at a constant speed.
Note: The constant speed doesn't have to be zero, so the object is not necessarily at rest. It can be moving at any speed, as long as the speed doesn't change. (If the speed changed, then the acceleration wouldn't be zero.)
We are to calculate the acceleration.
Answer:
-9.8 m/s²
Explanation:
Since the egg is in a free fall, it means that the force due to gravity will be equal to the normal force.
Now,
Force due to gravity: F_g = mg
Normal force; F_n = ma
Thus;
mg = ma
m will cancel out to get
g = a
Since it is a free fall motion, then gravity is negative;
-g = a
g has a constant value of 9.8 m/s². Thus;
a = -9.8 m/s²
Answer:
The percentage change in frequency is 10%.
Explanation:
Given that,
Amplitude decreases by 1/10 per second.
Resonance = 10 Hz
We need to calculate the change in frequency
Using formula of change in frequency
Put the value into the formula
We need to calculate the resonant frequency
Using formula of resonant frequency
Put the value into the formula
We need to calculate the percentage change in frequency
Using formula of percentage change in frequency
Hence, The percentage change in frequency is 10%.
Answer:
V = 0.074 m/s
Explanation:
given,
mass of the receiver, M = 96 Kg
mass of the ball, m = 0.42 Kg
initial speed of the ball, v = 17 m/s
initial speed of the receiver = 0 m/s
final speed.V = ?
using conservation of momentum
M u + m v = (M + m) V
0 + 0.42 x 17 = (96+0.42) V
96.42 V = 7.14
V = 0.074 m/s
hence, Speed after catching the ball is equal to 0.074 m/s
