Answer:

\boxed {\boxed {\sf 45 \ Joules}}

Explanation:

Work is the force the causes the movement or displacement of an object. It is the product of force and displacement.

W=Fd

The force is 15 Newtons and the displacement is 3 meters.

  • F= 15 N
  • d= 3 m

Substitute the values into the formula.

W= 15 \ N * 3 \ m

Multiply.

W= 45 \ N*m

1 Newton meter is equal to 1 Joule, so our answer of 45 Newton meters is equal to 45 Joules.

A 900 kg car travelling at 12 m/s due east collides with a 600 kg car travelling at 24 m/s due north. As a result of the collisi
katrin [286]

Calculate force of each car:

P1 = 900 kg x 12m/s = 10,800

P2= 600 x 24 = 14,400

Degree of travel = arctan(14,300/10800)

Degree of travel = 53.1 N of E

a person pushing a stroller starts from rest, uniformly accelerating at a rate of 0.500m/s^2. what is the velocity of the stroll
grandymaker [24]
You're going to use the constant acceleration motion equation for velocity and displacement:
(V)final²=(V)initial²+2a(Δx)

Given:
a=0.500m/s²
Δx=4.75m
(V)intial=0m
(V)final= UNKNOWN

(V)final= 2.179m/s
