Why is it possible to throw a 0.145 kg baseball much further than a 7 kg bowling ball?

1 answer:

7 0

It is possible to throw a 0.145 kg baseball much further than a 7 kg bowling ball, because the 0.145 kg baseball is of a smaller mass than the 7 kg bowling ball and it also offers less resistance to motion and hence it would go further than the 7 kg bowling ball.

Amy uses 20N of force to push a lawn mower 10 meters. How much work does she do? *

babunello [35]

She does 200J .

We know she uses 20N of force and 10m is the distance. We multiply both numbers and we are given our answer of 200J. Hope this was helpful. :)

Which runner has greater kinetic energy: a 45 kg runner moving at a speed of 7 m per second or a 93 kg runner moving at a

bagirrra123 [75]

Kinetic Energy = (1/2) (mass) (speed)

First runner: KE = (1/2) (45kg) (49 m/s) = 1,102.5 Joules

Second runner: KE = (1/2) (93kg) (9 m/s) = 418.5 Joules

The <em>first runner </em><em>has 163</em>% more kinetic energy than the second runner has.

If the mass of an object is 8 kg and its momentum is -80 kgm/s, what is its velocity?

Dimas [21]

An object's momentum is the product of its mass and its velocity:

p = mv

p is its momentum, m is its mass, and v is its velocity.

Given values:

p = -80kg×m/s

m = 8kg

Plug in these values and solve for v:

-80 = 8v

v = -10m/s
