Question

plz answer fast plzz

Answer 1

Answer:

As per the question the mass of the car m = 2500 kg

the acceleration of the car a = 1.3 m/s square

As per newton's second law of motion

we know that F = ma

where F is the force

here m = 2500 kg and a = 1.3 m/ s square

Hence F = 2500 kg *1.3 m/s square

=3250 N

here newton is the unit of force

we asked to calculate the force exerted by the barrier on the car

it can be explained by newton's third law of motion

As per newton's third law of motion action and reaction are equal and opposite the force exerted by one body on other is called action and the force imparted on it in turn is called reaction both will same in magnitude but their direction will be opposite as they act on two different bodies

here the force exerted by car on the barrier is 3250 N hence the force exerted on car due to the barrier is also 3250 N

Explanation:

I hope this answer helps u

Answer 2

Answer:

As per the second law of motion

F= MA

F= 2500 x1. 3

F=3250 N

It uses second law of motio
