BOARD PROBLEM A soldier, hiding in a 3.5-meter-deep hole, threw a grenade with an initial velocity of 28.0 m/s at a launching angle of 35° from the horizontal. A pile of sandbags, 3.0 meters in height, is located exactly 12.0 meters (horizontally) from where the soldier is. Set the ground surface as y = 0. (a) Will the sandbags be able to block the grenade? Show calculations that support your answer. (b) What will be the velocity of the grenade as soon as it hits the ground? (c) Disregarding the sandbags, if the grenade explodes 1.7 seconds after it was thrown, at what position, 7, will it explode? Express your answer in unit-vector form.

Geese migrate along north and south directions for well over a thousand kilometers in some cases traveling speeds up to about 100 km/h. If one such bird is flying at 100km/h relative to the air but there is a 34.0 km/h wind blowing from the west to east. A.) at what angle relative to the north-south direction should this bird head so that it will be traveling directly southward relative to the ground? Express answer in degrees b.) how long will it take the bird to cover a ground distance of 500 km from north to south? ( Note: Even on cloudy nights many birds navigate using the earth's magnetic field to fix the north-south direction)
1. The distance between home plate and the pitcher's mound in baseball is 60.5 ft. In MLB, baseballs are. pitched at about 90mph. Assume the ball is thrown perfectly horizontally, at 0°. How far in feet will the ball drop during its transit to home plate? Use g = 32 ft/s². (Note: this is why pitcher's mounds are raised.) 2.

You are 6 meters from the house and the roof of the house is 3 meters above the ground. Assuming you toss the pizza from ground level with an initial speed of 10 m/s at an angle of 60° (above the horizontal), how far onto the roof does the pizza land? Assume the roof is ﬂat. Give your answer to 2 signiﬁcant ﬁgures.
A baseball is hit into the air at an initial speed of 35.5 m/s and an angle of 52.3° above the horizontal. At the same time, the center fielder starts running and catches the ball on its way down when the ball is 0.964 m above the level at which it was hit. If the center fielder is initially 1.02 x 10² m from home plate, what must be his average speed? Number i Units
