30N
Explanation:
Given parameters:
Mass of object = 15kg
Acceleration = 2m/s
Unknown:
Force = ?
Solution:
Force is given as the product of mass and acceleration:
F = m x a
m is the mass
a is the acceleration
Inputting the parameters:
F = 15 x 2 = 30N
The unit of force is newtons, N .

Work = (force) x (distance)
62,500 joules = (boulder's weight) x (25 meters)
Divide each side by (25 meters) :
Boulder's weight = (62,500 joules) / (25 meters) = <u>2,500 newtons</u>
That's about 562 pounds.
Answer:
Scalar quantities are physical quantities which have a magnitude and direction.
e.g. in 5 km, 5 is the magnitude(number) and km is the unit.
some scalar quantities are mass, length, distance, speed, power, energy, temperature etc.
