F = applied force on the wheelbarrow in forward direction = 600 N

f = frictional force pushing in backward direction of wheelbarrow = ?

m = mass of the wheelbarrow = 28 kg

Since wheelbarrow moves forward at a constant velocity

a = acceleration of the wheelbarrow in forward direction = 0 m/s²

force equation for the motion of wheelbarrow in forward direction is given as

F - f = ma

inserting the above values in the formula

600 - f = (28) (0)

600 - f = 0

f = 600 N

hence the frictional force comes out to be 600 N

A ball bearing is projected vertically upwards from the ground with a velocity of 15ms. Calculate the time taken by the ball to

cupoosta [38]

Answer:

t = 3 [s]

Explanation:

To solve this problem we must use the following equation of kinematics.

$v_{f}=v_{o}-g*t$

where:

Vf = final velocity [m/s]

Vo = initial velocity = 15 [m/s]

g = gravity acceleration = 10 [m/s²]

t = time [s]

Now replacing we have:

$0 = 15 -10*t\\10*t=15\\t= 1.5[s]$

Note: In the equation above the gravity acceleration is negative, because the movement of the ball bearing is pointing againts the gravity acceleration.

The time calculated is only when the ball bearing reaches the highest elevation, and it will take the same time for descending, therefore the total time is:

t = 1.5 + 1.5 = 3 [s]

Hi, thank you for posting your question here at Brainly.

Electricity is the flow of electrons due to a potential difference called voltage. The electrons naturally flows from a higher to a lower potential. Thus, the electrons flows from the positive to the negative terminal.
