Q7. A 2kg ball is released from a height of 20m.
Vesnalui [34]

Answer:

Given,

Mass, m = 2kg

Height or distance, s = 20m

Initial velocity, u = 0m/s

Acceleration due to gravity, g = 10m/s (It is 9.8m/s but can be assumed 10m/s for simplifying calculations)

(Because the object is is just dropped)

Final velocity, v = ?

Solution

v^2 = u^2 + 2as (u^2 means u raised to power 2)

=> v^2 = 0^2 + 2*10*20

=> v^2 = 400

=> v = 20

Thus the velocity just before the body strikes the ground will be 20m/s.

What is the centripetal force
Lelechka [254]

Answer:90N

Explanation:

Mass=30kg

Centripetal acceleration=3m/s^2

centripetal force=mass x centripetal acceleration

Centripetal force=30 x 3

Centripetal force =90

Centripetal force =90N

A firecracker sitting on the ground explodes into two pieces. Immediately after the explosion, one of the pieces has momentum of
Misha Larkins [42]

Answer:

other part will move with momentum 0.5 kg m/s towards west

Explanation:

As we know that the during the explosion event the time interval is very small and there is no impulsive force on the firecracker during this time

so here we can say that the momentum will remains conserved during the this event

now if the initial momentum of the firecracker is zero

then the final momentum must be zero

so here we can say

P_1 + P_2 = 0

P_1 = 0.5 kg m/s towards east

now from above equation

P_2 = - P_1 = -0.5 kg m/s

so the other part will move with momentum 0.5 kg m/s towards west
