When you double the force acting on an object and keep the mass of the cart constant the acceleration is?
Doubled.
What if The force of friction acting on a cart on a ramp is exactly balanced by the force of gravity acting on the cart down the ramp?
The cart stays where it is and doesn't move.
When mass is added to a moving cart what happens to its acceleration?
The cart's acceleration will decrease as its mass increases. This is why you must exert progressively more force on a shopping cart to move it along as items are added to it. If you were to continue to add items to the cart but not change how hard you push it, the cart would eventually become "impossible" to push.
What will the motion of the cart be like when there is no force at all?
he do not do any motion
Why must the mass in the F equals ma include the hanging mass as well as the mass of cart?
because the mass must be constant with the mass of the same cart,0.27kg to ensure the force obtained more precisely and avoid the greater difference to calculate force
If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.
When you double the force acting on an object and keep the mass of the cart constant the acceleration is?
Doubled.
What if The force of friction acting on a cart on a ramp is exactly balanced by the force of gravity acting on the cart down the ramp?
The cart stays where it is and doesn't move.
What do you think will happen to the cart's acceleration when it is pulled with a constant net force?
The cart's acceleration will be directly proportional to the net force applied to it. If the force remains constant, the acceleration will also remain constant, assuming no other external factors are affecting the cart's motion.
When mass is added to a moving cart what happens to its acceleration?
The cart's acceleration will decrease as its mass increases. This is why you must exert progressively more force on a shopping cart to move it along as items are added to it.

If the force acting on a cart doubles what happens to the cart's motion?
it goes faster i assume.
What will the motion of the cart be like when there is no force at all?
he do not do any motion
Mariela used 45 N of force to stop a cart that was about to roll into Jamilett. It took Mariela 12 seconds to do so. What was the impulse acting on the cart?
die
What is the work being done the girl pulling her cart?
The force exerted by the girl in pulling the toy car is in the same direction as the distance covered when the force is applied.
Why must the mass in the F equals ma include the hanging mass as well as the mass of cart?
because the mass must be constant with the mass of the same cart,0.27kg to ensure the force obtained more precisely and avoid the greater difference to calculate force
Calculate the impulse of a 45 kg cart being pushed with a 5 N force for 10 s.?
If the force is constant (doesn't change over time), the impulse (change in momentum) is simply the product of force x time.
Cart is rolling down a special ramp where there is no friction at all What will happen if the amount of mass on the cart is increased?
The cart will move at a constant velocity.
