Force = (mass) x (acceleration)
= (2 kg) x (20 m/s²) = 40 newtons .
about 9 pounds .
Note: The ball can only accelerate during the short time
that the clubface is in contact with it. Once it leaves the
clubface, it can't accelerate any more.
Also ... that's one heckuva golf ball. It weighs about 4.4 pounds !
Answer
graph 2
Explanation
Velocity is the rate of change of displacement.
Velocity = (change in displacement)/(change is time)
In graph 2, the gradient of the curve is positive, indicating that the velocity is positive.
Acceleration is the rate of change of velocity.
The steepness of the slope of the same graph (graph 2) is decreasing. This shows that the velocity is decreasing hence a negative acceleration.
Answer:
d = 105 m
Explanation:
Speed of a car, v = 21 m/s
We need to find the distance traveled by the dar during those 5 s before it stops. Let the distance is d. It can be calculated as :
d = v × t
d = 21 m/s × 5 s
d = 105 m
So, it will cover 105 m before it stops.
Answer:
i may be wrong but the distance is 11 and the displacment is 73
Explanation:
They are produced in different processes and are detected in many differently.
