A space probe is coasting through space at a steady speed of 100p feet per second. the booster rocket fires for 1/2 seconds so t
aleksandr82 [10.1K]

Answer:

Acceleration: 9800 ft/s^2

Explanation:

The acceleration of an object is equal to the rate of change of velocity:

a=\frac{v-u}{t}

where

u is the initial velocity

v is the final velocity

t is the time taken for the velocity to change from u to v

For the space probe in this problem, we have:

u = 100 ft/s (initial velocity)

v = 5000 ft/s (final velocity)

t = 0.5 s (time taken)

Therefore, the acceleration is

a=\frac{5000-100}{0.5}=9800 ft/s^2

Mr. Claspell moves 100 N of avocados straight up 2.0 meters.
solniwko [45]

Answer:

see the various answers below

Explanation:

From the given details, we can see that we are required to solve for the work done.

1. Mr. Claspell moves 100 N of avocados straight up 2.0 meters.

Work done= Force*Distance

Work done= 100*2= 200Joules

2. The Flash tackles the Reverse-Flash and pushes him 3.0 meters using a force of 200 N.

Work done= Force*Distance

Work done= 200*3= 600Joules

3. Darth Vader moves a large rock using force. That force is 3.0 N and he moves the rock 15 meters.

Work done= Force*Distance

Work done= 3*15= 45Joules

4. Mario carries Princess Peach 45 meters away from Bowser’s Castle with a force of 5.0 N

Work done= Force*Distance

Work done= 5*45= 225Joules

5. A roller coaster car lifts a group of people 50 m to the top of the roller coaster with a force of 550 N.

Work done= Force*Distance

Work done= 550*50=27500Joules or 27.5kJ

An elevator accelerates upward at 1.2 m/s 2 . the acceleration of gravity is 9.8 m/s 2 . what is the upward force exerted by the
Marysya12 [62]
We can find the force by using the following formula;
N = ma +  mg
Fa = ma = 76 x 1.2 = 91.2
Fg = mg = 76 x 9.8 = 744.8
N = 91.2 + 744.8 = 836
So, the force is 836 N.
