Answer:
5295.3 N
Explanation:
According to law of momentum conservation, the change in momentum of the ball shall be from the momentum generated by the batter force
mv + P = mV
P = mV - mv = m(V - v)
Since the velocity of the ball before and after is in opposite direction, one of them is negative
P = 0.14(44.8 - (-19.5)) = 9 kg m/s
Hence the force exerted to generate such momentum within 1.7ms (0.0017s) is
F = P/t = 9/0.0017 = 5295.3 N
Answer:
it will take him 200secs to run to the shops
(btw 200 seconds is 3minutes and 20secs)
Explanation:
distance = speed x time
time = distance / speed
1200 ÷ 6 = 200
time = 200seconds

Answer:
No, we should not pay attention to these opinions. (Find the essay below)
Explanation:
Celebrities are people who are prominent or well known because of the work that they do. Actors and sports stars are rightly classified as celebrities because their work affords them a lot of exposure. We see them on television, the internet and social media, and hear about their deeds and accomplishments on the radio.
This group of people always have their opinions about life and other topics of interest which they air when interviewed or when they decide to volunteer the information on their own accord. Most times fans who love them value their opinion so much that they even adjust to them or view it as the standard. For these fans, celebrities are their role models. They tend to copy their hairstyles, modes of dressing, and their opinions! Advertisers key to this fact when they use them to promote their goods.
It is very wrong to hold the opinions and actions of celebrities as the gold standard because they are imperfect and are prone to mistakes. Celebrities are just like any other one of us who have opinions or behave in ways that are sometimes wrong. Copying their every move, action, and opinions would be potentially damaging to us. Their opinions should be taken with a pinch of salt.
It is important that while fans maintain the love they have for their favorite celebrities, they also endeavor to have a mind of their own. Each person should know what works for him or her and live by such. It would be a great mistake to be easily carried away by the opinions of others.
Conclusively, balance is key. Love for celebrities should never cloud an individual's thinking. When this is done, future heartaches that come from adhering to wrong opinions can be avoided.
