Answer:
50.2 meters
Explanation:
When an object falls, it goes a distance d in time t according to the formula:
d is the distance in meter, g is the acceleration due to gravity with the value of 9.8
, t is the time in seconds
Therefore, 
d= 50.176 ≈ 50.2m
Answer:
Explanation:
I'm assuming the units for force and mass are Newtons and kilograms, respectively.
Rearranging Newton's first law (F=m*a) to solve for acceleration:
F=m*a
The acceleration is 4 meters per second squared and was found by rearranging Newton's first law in order to solve for acceleration.
Answer:
14.1 kg
Explanation:
Given:
Length=7.00inches
Width=3.63 inches
Height=1.75 inches
density = 19,300 kg/m3.
We can convert the given parameters to metre for unit consistency
But we know 1 inches= 0.0254 metre
✓Then Length l=7.00inches
=7×0.0254 metre=0.1778m
✓Width w =3.63 inches
==3.63 ×0.0254 metre=0.092m
✓Height h =1.75 inches
=1.75 ×0.0254 metre=0.0445 m
But Mass= density × volume
Volume= Length× width×height
Mass= density× Length× width×height
= 19300kg/m³×0.1778×0.0922×0.0445
=14.1 kg
Therefore, the mass of the gold bar is 14.1 kg
KE=1/2mv^2
So from the given information me can plug in the values and find the KE or Kinetic Energy for the canoe;
KE=1/2(17kg)(3m/s)^2
KE=8.5kg*9m^2s^2= 76.5J of Kinetic Energy
Hope this helps, any questions please just ask. Thank you.
