One of the equations for force is: Force = mass × acceleration.
The force and mass are given and so:
F=15N
m=10kg
By plugging in these values we obtain:
So the acceleration is a=1.5m/s^2
Static friction and normal force? I would Google to double check if I'm right.
<span>Work equals
force times distance. When you move an object, you are exerting a force onto
it. By exerting a force on the object, you are actually displacing it from its
initial position. You cannot apply force to the object without altering its
position. Keep in mind that when you exert work, you are exerting energy too. So
the work must have a unit in joules in SI units. Force is in newtons or
kilogram meter per second squared. And distance is in meters. So you will have
newton-meter or joules. </span>
Answer:
7 s / 3600 s/hr = 0.001944444444... = 0.0019 hr
a = (vf - vi) / t = (70 - 0) / 0.0019 = 36000 km/hr²
