From the calculation, the acceleration of the body is 26m/s^2.
<h3>What is motion under gravity?</h3>
When an object is thrown up or down, the motion of the body is influenced by the gravitational pull on the body.
Now;
Given that;
v = 39 m/s
t = 1.5 s
u = 0 m/s
a = ?
v = u + at
v = at
a = v/t
a = 39 m/s/1.5 s
a = 26m/s^2

0
Explanation:
the positive cancels out the negative area
Answer:
50J
Explanation:
Potential energy = mass (kg) * gravitational accelerations (10N on earth) * height
250 g in kg = 0.25
0.25 * 10 * 20 = 50 J
Answer:
Acceleration = 0.5 m/s²
Explanation:
Given the following data;
Initial velocity, u = 1m/s
Final velocity, v = 3m/s
Time, t = 4 seconds
To find acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;


Substituting into the equation, we have;
Acceleration = (3 - 1)/4
Acceleration = 2/4
Acceleration = 0.5 m/s²
Answer: Hubble's Law
Explanation: Hubble's law that states that the farther away a galaxy is, the faster it is moving away from us
