A box weighing 200N is pushed on a horizontal floor. What acceleration will result if a horizontal force of 100N is applied on t
Bogdan [553]

Answer:

the friction force in the reverse direction is 200 *0.4=80 N.

the net forward force acting on the box is therefore

Fnet= 100 - 80  N

= 20 N

acceleration = Fnet / mass

=Fnet *g/(weight)

=20 *9.8/200 = 0.98 m/s^2

A ball is thrown vertically upwards with a velocity of 9.8 m/s. Its velocity after 1 second will be
Reil [10]

\LARGE{ \underline{\underline{ \purple{ \bf{Required \: answer:}}}}}

GiveN:

  • Initial velocity = 9.8 m/s²
  • Accleration due to gravity = -9.8 m/s²
  • Time taken = 1 s

To FinD:

  • Final velocity of the ball?

Step-by-step Explanation:

Using the first Equation of motion,

⇒ v = u + gt

⇒ v = 9.8 + -9.8(1)

⇒ v = 0 m/s

The final velocity is hence <u>0</u><u> </u><u>m</u><u>/</u><u>s</u><u>.</u>

<h3>Note:</h3>

  • While solving questions of under gravity motions using equations of motion, remember the sign convection to avoid mistakes.
  • You can consider positive above the ground and negative for towards it.
