Answer:
Being an elastic object, rubber ball will be an ideal choice as it will bounce off the bowling pit and will experience a large change in momentum in comparison with the beanbag which will either slow down or come to a halt upon hitting a bowling pit. That is why rubber ball will experience a greater impulse and the bowling pin will experience the negative impulse of the rubber ball.
For Rubber Ball
Upon elastic collision it will reverses the direction and move with velocity equal or less then original
change in momentum = P
For Beanbag
value of impulse will large if velocity is zero.
Explanation:
Radial acceleration is given by
where
then
Now
Using the relation
Putting into rpm
Answer: the horizontal component of total momentum
Explanation:
Since the open cart is rolling to the left on the horizontal surface, the quantity that has the same value just before and just after the package lands in the cart is the horizontal component of total momentum.
Momentum, is the product of the mass of a particle and the velocity of the particle. The change of momentum depends on the force which acts on it. The addition of the the individual momenta is the total momentum.
Scientific evidence supports a new idea
Answer:
Explanation:
conversion of 2.5 days to seconds
2.5 days =2.5 days*24 hours*3600 seconds
2.5 days=216000seconds
b) conversion of 25 km to mm
1 km=1000000 mm
therefore
25 km=25*1000000=25000000 mm
c) conversion 22 g to kg
1000 g=1 kg
therefore
22 g=22/1000=0.022 kg
