What force will a car hit a tree If the car has a mass of 3000kg and is accelerating at a rate of 2m/s2?

Answer 1

According to Newton's second law of motion, the acceleration of a body is directly proportional to the force acting on the body and inversely proportional to its mass. The formula for this law is #a# = #"F"/m#, from which we get the formula #"F"# = #ma#. When mass is in kg and acceleration is in #"m/s/s"# or #"m/s"^2#, the unit of force is #"kgm/s"^2#, which is read as kiligram-meter per second squared. This unit is replaced with an N in honor of Isaac Newton. Your problem can be solved as follows:

Known/Unknown: #m# = #"3000kg"# #a# = #"2m/s"^2#

Equation: #"F"# = #ma#

Solution: #"F"# = #ma# = #"3000kg"# x #"2m/s"^2# = #"6000kgm/s"^2# = #"6000N"#

The force with which the car will hit the tree can be calculated using Newton's second law of motion, which is expressed as force (F) equals mass (m) multiplied by acceleration (a). In this case, the force (F) equals the mass of the car (3000 kg) multiplied by the acceleration (2 m/s²).

[ F = m \times a ] [ F = 3000 , \text{kg} \times 2 , \text{m/s}^2 ] [ F = 6000 , \text{N} ]

Therefore, the force with which the car will hit the tree is 6000 Newtons.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
