Answer:

1317.4 m

Explanation:

We are given that

Angle=\alpha=40.8^{\circ}

Initial speed =v_0=346m/s

We have to find the horizontal distance covered  by the shell after 5.03 s.

Horizontal component of initial speed=v_{ox}=v_0cos\theta=346cos40.8=261.9m/s

Vertical component of initial speed=v_{oy}=346sin40.8=226.1m/s

Time=t=5.03 s

Horizontal distance =Horizontal\;velocity\times time

Using the  formula

Horizontal distance=261.9\times 5.03

Horizontal distance=1317.4 m

Hence, the horizontal distance covered by the shell=1317.4 m

For each data point in the table, calculate the ratio of gravitational force to mass. What are the Ratios and what do you notice
BaLLatris [955]

Number of Washers . . . Total Mass . . . Total Force . . . Ratio

1 ................................................0.6 kg ................5.9 N ........... 9.83 N/kg

2 ................................................1.2 kg ...............11.8 N ............ 9.83 N/kg

3 ................................................1.8 kg ..............17.6 N ............. 9.78 N/kg

4 ...............................................2.5 kg .............24.5 N ............. 9.80 N/kg  

5 ...............................................3.2 kg ..............31.4 N ............. 9.81 N/kg

The ratios are listed in the table.  

The ratio seems to be constant, and not depend on the number of washers or the total mass.  It's always about 9.8 Newtons per kilogram of mass.  There must be something special about that number.
