A cricket ball is projected vertically upward what kind of acceleration is acting on the ball?
a cricket ball is projected vertically upward direction.what kind of acceleration is acting on it
What is the acceleration of a ball at the top of its trajectory when thrown straight upward?
zero
If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?
The acceleration is the same, which is the acceleration due to gravity. About 10m/s^2
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
What is the downward acceleration of projectile that is released from a missile accelerating upward at 9.8?
upword acceleration is -9.8 and downword is 9.8m/s^2
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].

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 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.

Can a body have acceleration while at rest give example?
a body projected upward is in rest at the top most point, but acceleration is not zero
Can an object have velocity and acceleration vectors that point in opposite directions?
Yes it can, and it's really easy. -- A stone tossed upward, before it peaks and starts falling, has upward velocity and downward acceleration. -- A car driving east and slowing for a stop-sign has eastward velocity and westward acceleration.
