Astone is catapulted at time t = 0, with an initial velocity of magnitude 19.9 m/s and at an angle of 39.9° above the horizontal. what are the magnitudes of the (a) horizontal and (b) vertical components of its displacement from the catapult site at t = 1.03 s? repeat for the (c) horizontal and (d) vertical components at t = 1.71 s, and for the (e) horizontal and (f) vertical components at t = 5.44 s. assume that the catapult is positioned on a plain horizontal ground.

Part a)

Part b)

Part c)

Part d)

Part e)

Part f)

Explanation:

As we know that catapult is projected with speed 19.9 m/s

so here we have

similarly we have

Part a)

Horizontal displacement in 1.03 s

Part b)

Vertical direction we have

Part c)

Horizontal displacement in 1.71 s

Part d)

Vertical direction we have

Part e)

Horizontal displacement in 5.44 s

Part f)

Vertical direction we have

ill do it for 100, also this isnt 80 its 40

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle
