What is the magnitude of the upward acceleration of the load of bricks?
The magnitude of the upward acceleration of the load of bricks is the measure of how fast the load is moving upwards.
What is the net force on a bag pulled down by gravity with 18 newtons and pulled upward by a rope with 18 newtons?
Well unless this is a trick question it is 0 Newtons as the 2 forces cancel themselves out.
When upward is positive then acceleration sign is?
Positive if the acceleration is also upwards directed, and if you are considering a one dimensional space where you thus only have upwards and downwards as directions. Otherwise you need to more information before you able to answer this question.
What is the downward acceleration of projectile that is released from a missile accelerating upward at 9.8?
The downward acceleration of the projectile released from the missile would still be due to gravity, which is approximately 9.8 m/s^2 on Earth. This acceleration is independent of the initial upward acceleration of the missile.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
What is the acceleration of a 20 kg pail of cement that is pulled upward with a force of 400 n?
Gravitational pull on the pail = 20 [kg] * 9.8 [m / s2]. Net force upward = 300 [N] - 20 [kg] * 9.8 [m / s2] = 104 [N]. (recall that 1 [N] = 1 [kg] * 1 [m / s2]) Mass, M = 20 [kg] By Newton's 2nd law of motion, F = M * A. upward acceleration, A = F / M = 104 [N] / 20 [kg] = 5.2 [m/s2].
What is the magnitude of the upward acceleration of the load of bricks?
The magnitude of the upward acceleration of the load of bricks is the measure of how fast the load is moving upwards.

What does an upward sloping diagonal line mean in a velocity vs time graph?
An upward sloping diagonal line on a velocity vs. time graph represents constant acceleration. The steeper the slope, the greater the acceleration.
An object thrown upward has zero acceleration at the highest point?
No, the acceleration at the highest point is never 0.
What is the upward acceleration of a falling object?
If you are ignoring wind and other variables then the upward acceleration is negative velocity caused by gravity. So in most cases (-9.8 m)/(s^2)
What is the downward acceleration of projectile that is released from a missile accelerating upward at 9.8?
The downward acceleration of the projectile released from the missile would still be due to gravity, which is approximately 9.8 m/s^2 on Earth. This acceleration is independent of the initial upward acceleration of the missile.
What is the acceleration of a 8kg baby pulled upward with a force of 150 newtons?
F = M a a = F / M = 150 / 8 = 18.75 meters per second2 That's almost 2 G's . . . no way to handle a baby.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
A cricket ball is projected vertically upward what kind of acceleration is acting on the ball?
When a cricket ball is projected vertically upward, the acceleration acting on the ball is gravitational acceleration directed downward. This causes the ball to slow down until it reaches the highest point of its trajectory, then it accelerates back downward due to gravity.
