Ionic compound is the answer
Remember, in order to calculate the weight on earth, we need to multiply the mass of the object with the force of Gravity (9.8 m/s^2 on earth)
so, her weight would be:
48 x 9.8 = 470.4 >>>>>>> Will be 470 if we round it to the nearest whole number.
Gpe= 90* 9.81 * 15 = 13243.5 Joules
KE= 13243.5 =1/2 m v^2
v^2= 295.3
v= 17.2 m/s
Since the acceleration is constant, the average velocity is simply the average of the initial and final velocities of the body:
We can proof that the distance covered by the body moving at constant average velocity is equal to the distance covered by the body moving at constant acceleration a:
- body moving at constant velocity : distance is given by
- body moving at constant acceleration : distance is given by
Im confused bc im not sure if this is a full question
