The distance travelled by the car is 85 m

Explanation:

The car in this problem here is travelling by uniform motion (so, at constant velocity and constant speed). Therefore, the distance covered by the car after a time t is given by:

d=vt

where

d is the distance covered

v is the speed

t is the time

For the car in this problem we have

v = 34 m/s

t = 2.5 s

Substituting into the formula, we find

d=(34)(2.5)=85 m

So, the car has travelled for 85 m.

an athlete whirls a 7.00 kg hammer tied to the end of a 1.3 m chain in a horizontal circle the hammer moves at the rate of 1.0 r
ElenaW [278]

Answer:

The answer to your question is a = 1.3 m/s²

Explanation:

Centripetal acceleration is the motion of a body that transverse a circular path.

Data

mass = 7 kg

radius = r = 1.3 m

angular rate = w = 1.0 rev/s

centripetal acceleration = a = ?

Formula

a = rw²

Substitution

a = (1.3)(1)²

Simplification and result

a = 1.3 m/s²

expeople1 [14]

Answer:

Explanation:

You are going to lift and press down on the 200 N many times and move only a short distance. The reward is that slowly but surely you will lift a very heavy load -- one that cannot be managed any other way but by the hydraulic jack.
