Answer:
a) 256 ft
b) 32 ft/s
c) -32 ft/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 32 ft/s²
Maximum height = 256 ft
When s = 240 ft
Speed of the ball at 240 ft is 32 ft/s while going up
Now this will be the velocity of the ball when it reaches 240 ft, which will be considered as the initial velocity
Now, initial velocity will be considered as zero
Speed of the ball at 240 ft is -32 ft/s while going down
The net force acting on the bicyclist is 11.022 Newton.
<u>Given the following data:</u>
- Mass of bicyclist = 66 kg
- Initial velocity = 0.50 m/s
- Initial velocity = 1.50 m/s
- Distance traveled = 6.0 meters
To find the net force acting on the bicyclist, we would apply Newton's Second Law of Motion:
Mathematically, Newton's Second Law of Motion is given by this formula;
×
First of all, we would determine the acceleration by using the third equation of motion;
Acceleration, a = 0.167
Now, we can find the net force acting on the bicyclist:
×
<em>Force </em><em>= </em><em>11.022 Newton</em>
Therefore, the net force acting on the bicyclist is 11.022 Newton.

Answer:
Explanation:
I assume that by "velocity" you refer to the average velocity of the man during the trip.
In that case, we have the following data:
(average velocity)
s = 0.8 km = 800 m (distance covered by the man)
Therefore, we can find the total time of the trip by using
Now, we know that the motion during this trip is a uniformly accelerated motion, so we can find the acceleration by using the suvat equation:
where
u = 0 is the initial velocity (the man starts from rest)
a is the acceleration
Using s = 800 m and t = 114.2 s, we find:
