A catapult launches a rocket at an angle of 53.0 above the horizontal with an initial speed of 100 m/s. The rocket engine immediately starts a burn, and for 3.00 s the rocket moves along its initial line of motion with an acceleration of 30.0 m/s2. Then its engine fails, and the rocket proceeds to move in free fall. Find (a) the maximum altitude reached by the rocket, (b) its total time of flight, and (c) its horizontal range.
A rocket is launched at an angle of 53.0 above the horizontal with an initial speed of 100. m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. Find (a) the maximum altitude reached by the rocket, (b) its total time of flight, and (c) its horizontal range.
A truck loaded with cannonball watermelons stops suddenly to avoid running over the edge of a washed-out bridge (Fig. P3.74). The quick stop causes a number of melons to fly off the truck. One melon rolls over the edge with an initial speed i = 10.0 m/s in the horizontal direction. A cross section of the bank has the shape of the bottom half of a parabola with its vertex at the edge of the road, and with the equation y2 = (16.0 m) x, where x and y are measured in meters. What are the x- and y-coordinates of the melon when it splatters on the bank? Figure P3.74 The blue dashed curve shows the parabolic shape of the bank.
2. A projectile is launched with an initial speed of 21.8 m/s at an angle of 35.0-degrees above the horizontal. (a) Determine the time of flight of the projectile. (b) Determine the peak height of the projectile. (c) Determine the horizontal displacement of the projectile.
1-Imagine that during a storm, raindrops are falling straight down with speed u, measured relative to the ground. Let’s say you are driving east in your car with speed v (relative to the ground). From your perspective, at what angle from the vertical are the raindrops moving? Give your answer symbolically in terms of the variables u and v. note: Drawing necessary for this question
Immediately after the bouncing golf ball leaves the floor, its components of velocity are Vx = 0.888 m/s, and Vy = 3.504 m/s. Determine the horizontal distance (meters) from the point where the ball left the floor to the point where it hits the floor again. Answer is 0.634. No other answer thanks.
A projectile is shot from the edge of a cliff 115 m above ground level with an initial speed of v0 = 56 m/s at an angle of 35.0∘ with the horizontal, as shown in the figure A-Determine the time taken by the projectile to hit point P at ground level. B-Determine the distance X of point P from the base of the vertical cliff.

During a fireworks display, a shell is shot into the air with an initial speed of 91.55 m/s at an angle of theta degrees above the horizontal. The fuse is timed to 8.21 seconds for the shell just as it reaches its highest point above the ground. If the horizontal displacement of the shell is 149.68 meters when it explodes, what is the height (in unit of meters) when the shell explodes? You must use g = 9.8 m/s2.
A projectile is fired with an initial speed of 36.2 m/s at an angle of 42.3 ° above the horizontal on a long flat firing range. Determine the maximum height reached by the projectile. Express answer using three significant figures. Determine the total time in the air. Express answer using three significant figures. Determine the total horizontal distance covered (that is, the range) Determine the speed of the projectile 2.00 s after firing.
You launch a projectile from level ground at speed 22.0 at an angle of 29.0 above the horizontal. How far will the projectile travel horizontally, assuming it lands at the same height it was launched from (Δy = 0m)? (assume g = -9.81 m/s2)
A cat leaps to try to catch a bird. If the cat's jump was at an angle 59.73 degree above the horizontal and its initial velocity was 26.46 m/s. At what time (in seconds) does it reach the highest point of the jump? You should neglect air resistance and use g = 9.8 m/s2.
