=0.5 x40
<span>= (calculate it) </span>
<span>2. F= -.45 x 41 </span>
<span>= </span>
<span>3. F=20 x 12 </span>
<span>= </span>
<span>4. F=50 x 30 </span>
<span>= </span>
<span>I believe you can go on from here, remember its easy </span>
<span>for the last 2 just rearange the formual </span>
<span>for 9 it will be a=F/m and 10. m=f/a </span>
Answer:
19,551 J!
Explanation:
The formula is PE = ham (h=height, a= acceleration or 9.8, m= mass)
PE = (95)(9.8)(21)
PE = 19,551 Joules
- Kinetic Energy of an object is the measure of the work an object can do by virtue of its motions..
- Where KE is the kinetic energy, m is the body’s mass, and v is the body’s velocity.
- Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts..
Where,
. m is the mass in kilograms
. g is the acceleration due to gravity
. h is the height in meters
Hope it helpz~ uh..
