Answer:
Total mechanical energy = 225 J
Explanation:
Given:
Mass of duck (m) = 2 kg
Speed of duck (v)= 5 m/s
Height of duck from ground (h) = 10 m
Gravitation acceleration (g) = 10 m/s²
Find:
Total mechanical energy
Computation:
Total mechanical energy = Kinetic energy + Potential energy
Total mechanical energy = (1/2)mv² + mgh
Total mechanical energy = (1/2)(2)(5)² + (2)(10)(10)
Total mechanical energy = 25 + 200
Total mechanical energy = 225 J
If you know 0 C= 32 F, it is greater at 48 F
A car with a velocity of 22 m/s is accelerated at a rate of 1.6 
for 6.8s has the final velocity t be 32.88 m/s.
The acceleration means the amount of velocity changing per unit time.
The given data:
initial velocity, u = 22 m/s
time, t = 6.8 s
acceleration, a = 1.6
We will be using the equation of motion:
v = u + at
The final velocity become 32.88 m/s.

We are given with 98 Newton weight of an object on the surface of the earth with an acceleration equal to 9.8 m/s2. This means the mass of the object is equal to 98/9.8 or 10 kg. Hence the weight of the object 10,000 kilometers above sea level where acceleration is 1.49 m/s2 is 14.9 Newtons.
