Question

so a few parts to this section's question; nevertheless:..

You throw a ball with a speed of 25.3 m/s at an angle of 42 degrees above the horizontal directly towards a wall. The wall is 21.8 m from the release point of the ball. How far above the release point does the ball hit the wall ?

A) 13.95 m  

B) 13.04 m

C) 26.22 m

D) 13.67 m

Next part..

An 8.5 kg object passes through the origin with a velocity of 42 m/s parallel to the x-axis. It experiences a constant 19 N force in the direction of the positive y-axis. Calculate the position of the object after 15 s have elapsed.

A) (630 m, 251. m)

B) (881. m, 251. m)

C) (630 m, 16.8 m)

D) (680 m, 50.3 m)

And the last part:..

Three blocks are connected, as shown in Fig. 40, on a horizontal frictionless table and pulled to the right with a force T3 = 6.5 N. If m1 = 1.2 kg, and m2 = 2.4 kg, and m3 = 3.1 kg, calculate the tensions T1 and T2

A) T1 = 1.16 N, T2 = 3.49 N

B) T1 = 6.5 N, T2 = 3.49 N

C) T1 = 6.5 N, T2 = 2.33 N

D) T1 = 1.16 N, T2 = 1.16 N
