3 Dynamic Physics Questions Urgent Help Needed!
Problem1
An object of 6kg is moving towards the south. The resulting force that the object has is 12 Newtons towards the north. What is the acceleration of the object?
f=ma
fg=mg
The question is wrong?
Problem2
A kid is pulling a wagon of 10kg with 40 Newtons of force at an acceleration 3.5m/s^2. There is 3 Newtons of friction.
How do you find the angle at which the child is pulling the wagon at?
f=ma
fg=mg
don't even know where to start
Problem3
There is a helicopter that weighs 15000kg lifting a car of 4500kg with a cable below it. If it where to move upwards at acceleration of 1.4m/s^2 what would be the necessary force required by the helicopters blades?
What is the force on the cable lifting the car?
f=ma
fg=mg
add the two weights find the force of gravity and then find the resulting force and add them?
Any help at all is greatly appreciated thanks for your time and effort!
