What engine thrust is required for a rocket of mass 35 kg to leave the launching pad? 3.5 N. 35 N. 351 N. 3,500 N. 35,000 N.
soldi70 [24.7K]

In order for the object to move upward, it needs an upward force
that's at least equal to its own weight.

Weight = (mass) x (gravity) = (35 kg) x (9.8 m/s²) = 343 N.

The engine thrust has to be more than 343 N.

Alfred pushes on a heavy box, but cannot move it. The box has a lot of _____. inertia motion friction gravity
77julia77 [94]

Answer:

Inertia

Explanation:

Inertia is best defined as the ability of an object to resist a change in position or movement. That is why when an object has a higher mass, the higher the inertia. Imagine an oncoming truck that is fully loaded versus you. The tendency for the truck to change its movement would be difficult because of its its mass. It has a lot of inertia.

A 1,000 kg ball traveling at 5 m/s would have kinetic energy
MatroZZZ [7]

Answer:

12500 J = 12.5 kJ

Explanation:

Kinetic energy is the energy possessed by a moving object solely due to its motion.

You can get the K.E. of an object using the equation,

K.E. =  (1/2)mv²

So you get, for ball

K.E. =  (1/2)×1000×5²  = 12500 J = 12.5 kJ

Answer:

Force = 1400N

Displacement = 2.5 m

work done = F×D

=1400×2.5

= 3500 joule
