Answer: 400 joules.

Explanation:

The minimal force needed to lift a 100N block is a force of 100N.

Now, work is defined as a movement done by a force, so we can write the work as:

W = F*d where F is the force and d is the distance traveled, in this case d = 4m so we have:

W = 100N*4m = 400 joules

Two heavy objects of masses 1 kg and 2 kg are moving towards each other under
SOVA2 [1]

The acceleration of the body in terms of the gravitational constant G is G.

According to Newton's law of universal gravitation;

F = Gm1m2/r^2

G = gravitational constant

m1 = mass of the first body

m2 = mass of the second body

r = distance between the two bodies

Substituting values to find the force on the two bodies;

F = G × 1  × 2/1^2

F = 2G

For the 2 Kg mass

F = ma

m = mass

a = acceleration

F = gravitational force

Hence,

2G = 2a

a = 2G/2

a = G

Find the displacement of a car that accelerates at -6m/s2 for 5 sec to a final velocity of 60m/s.
Anvisha [2.4K]

Answer:

Explanation:

2as=vf²-vi²

2as=(60)²-0²

2as=3600 m/s

s=3600/2*a

s=3600/2*(-6)

s=3600/-12

s=-300 m
