Answer:
50.2 meters
Explanation:
When an object falls, it goes a distance d in time t according to the formula:
d is the distance in meter, g is the acceleration due to gravity with the value of 9.8 , t is the time in seconds
Therefore,
d= 50.176 ≈ 50.2m
Answer:
negative acceleration of 4m/s²
Explanation:
Given parameters:
Initial velocity = 66m/s
Final velocity = 26m/s
Time taken = 10s
Unknown:
Description of the acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time.
It is mathematically expressed as;
acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Now insert the parameters and solve;
Acceleration = = -4m/s²
So, we see a negative acceleration of 4m/s²
