Answer:
For the car to move with constant velocity the additional force required is
Explanation:
From the question we are told that
The net force of the car is
Generally the total force acting on the car is the net force plus the force due to gravity acting in direction of the car (Let denote it as )
So the total force acting on the car is mathematically represented as
Here this F representing the total force can be mathematically represented as
Now for constant velocity to be attained, the acceleration of the car will be zero
So at constant velocity
=>
So
=>
=>
Answer:
74.529 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.8 m/s²
For first ball
For second ball
As the displacement is equal
So, height of the building is 74.529 m
