Answer:
Mechanical energy = 3.92 J
exactly 3.92 j
Explanation:
As we know that mechanical energy is sum of kinetic energy and potential energy of the system
so here we can say that mechanical energy is sum of kinetic energy of ball and its potential energy
Since ball is at rest so kinetic energy of the ball must be ZERO
Now for potential energy we know that

now we know
m = 0.2 kg
h = 2 m
now for potential ene'rgy


so mechanical energy is given as
Mechanical Energy = 3.92 + 0 = 3.92 J

Answer:
41.02m
Explanation:
Given parameters:
Initial velocity = 0m/s
Final velocity = 96km/hr
Time taken = 3.07s
Unknown:
Distance traveled by the time the final speed was achieved = ?
Solution:
To solve this problem, we first find the acceleration of the car;
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Now convert the the final velocity to m/s;
96km/hr to m/s;
1 km/hr = 0.278m/s
96km/hr = 96 x 0.278 = 26.7m/s
Now;
Acceleration =
= 8.69m/s²
So;
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance
26.7² = 0² + 2 x 8.69 x s
712.89 = 17.38s
s = 41.02m
