Answer:
750 force
Explanation:
I have never worked with force but I can guess using the formula. 1500, which is the mass, multiplied by the acceleration, 0.5, would equal 750 force, if being applied by the equation listed, Force= mass×acceleration
Answer:
Explanation:
The <u>initial</u> vertical velocity is 540sin55° = 442.342103... 442 m/s
The <u>initial</u> horizontal velocity is 540cos55° = 309.731275... 310 m/s
In the real world, both initial velocities would be reduced by air resistance and vertical velocity will be altered by gravity.
Answer: impulse and momentum
Explanation:
Answer:
1 m/s
Explanation:
Po = Pf
(0.050kg)(9 m/s) + (0.030kg)(v2) = (0.05kg + 0.030)(6 m/s)
0.45 kgm/s + (0.030kg)(v2) = 0.48 kgm/s
(0.030kg)(v2) = 0.03 kgm/s
v2 = 1 m/s
Water is, indeed, an exception. Normally when temperature drops, material shrinks. Water doesn't, water expands instead.
