Question

Автомобиль массой 1 т едет по прямой горизонтальной дороге и увеличивает скорость с 36 км\ч до 72 км\ч за 10 с.Найти силу,сообщающую ускорение автомобилю

Answer 1

M=10^3kg
v0=10m/s
v=20m/s
t=10s
F=?
F=ma
a=(v-vo)/t
a=1m/s^2
F=10^3*1=10^3N

Answer 2

Calculation of the Force

To find the force that imparts acceleration to the car, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Given: - Mass of the car = 1 ton = 1000 kg - Initial velocity = 36 km/h -
