Answer:
Average acceleration, 
Explanation:
Given that,
Initial velocity, u = 0 km/h
Final velocity, v = 100 km/h = 27.77 m/s
Time, t = 10 s
We need to find the average acceleration of the vehicle. It is given by the change in velocity divided by time. Som,
So, its average acceleration is 
.

Answer:
26.2 m/s
Explanation:
We can find the speed of the cannonball just by analyzing its vertical motion. In fact, the initial vertical velocity is
(1)
where u is the initial speed and 
is the angle of projection.
We can therefore use the following suvat equation for the vertical motion of the ball:
where 
is the vertical velocity at time t, and 
is the acceleration of gravity. The time of flight is 3.78 s, so we know that the ball reaches its maximum height at half this time:
And at the maximum height, the vertical velocity is zero:
Substituting these values, we find the initial vertical velocity:
And using eq.(1) we now find the initial speed:
Answer:
(a) 1/60
(b) Yes, it was unusual.
Explanation:
Number that went to the right field = 19
Number that went to the right center field = 18
Number that went to the center field = 12
Number that went to the left center field = 10
Number that went to the left field = 1
Total number of home runs = 60
(a) The probability that a randomly selected home run was hit to left field is
P(left field) = 1/60
(b) It was unusual because whenever a player hit a home run, it most times went to the right field,which is why the right field had the highest probability, 19/60.
On the other hand, it went to the left field the least number of times, which is why the left field had the least probability, 1/60.
So, it was unusual.
