A projectile is launched with an initial speed of 44.0 m/s at an angle of 31.0° above the horizontal. The projectile lands on a hillside 3.60 s later. Neglect air friction. (Assume that the +x-axis is to the right and the +y-axis is up along the page.) a) What is the projectile's velocity at the highest point of its trajectory? magnitude m/s direction ° counterclockwise from the +x-axis (b) What is the straight-line distance from where the projectile was launched to where it hits its target?

A smart ball, with a speedometer, is kicked with an initial speed of 37.0 m/s, then follows a projectile trajectory as shown. The speedometer recorded that the ball's lowest speed along its trajectory (at the highest point) is 28.0 m/s. What is the ball's initial launch angle measured in degrees? Origin y L

A student launches a physics textbook out of a cannon. For maximum distance, they launch it at a 45° angle, with an initial speed of vị = 80 m/s. If it starts from ground level, how high is the textbook when it is 20 m away horizontally from the cannon? Express your answer with the appropriate units. HA h = Value Units Submit Request Answer

When the dried-up seed pod of a scotch broom plant bursts open, it shoots out the seed with an initial velocity of 2.69 m/s at an angle of 63.5∘ above the horizontal.A: If the seed pod is 0.455m above the ground, how long does it take for the seed to land?B: What horizontal distance does it cover during its flight?

The circus manager wants to make the stunt more dramatic by firing the stuntman through a hoop 9.0 m high then land in a safety net at the same height as the cannon. The cannon’s angle is 45.0° and the velocity is 21.0 m/s. The manager needs to know where to place the hoop and safety net.a) How far from the cannon should the safety net be placed?b) What is the time required to reach the height of the hoop?c) How far from the cannon should the hoop be placed?d) Sketch the setup of the stunt showing the location of the cannon, hoop and net?

Kara is setting up a tee-shirt cannon for a community event. The angle of the cannon can be adjusted, but all projectiles leave the cannon at 25 meters per second. If Kara sets the angle of the cannon to be 20.o above horizontal, what will be the range of the projectiles?   64 m   61 m   41 m   25 m

John and Mary are skating at an ice rink. John skates at a constant speed of 6.6 m/s, with respect to the ice surface, directly south. Mary skates at a constant speed of 12.3 m/s in a direction of 28° west of south, with respect to the ice. What are the magnitude and direction of Mary's velocity with respect to John? Give the direction as measured relative to due south. magnitude m/s direction ° west of south

A)  With what speed, in meters per second, does the stone strike the ground? vf=

A golfer hits a ball with an initial speed of 30.0 m/s at an angle of 50.0oabove the horizontal. The ball lands on a green that is 5.00 m above the level where the ball was struck. a) How long is the ball in the air? b) How far has the ball traveled in the horizontal direction when it lands? c) What is the speed and direction of motion of the ball just before it lands?

A projectile is launched at ground level with an intial vertical velocity of 25.0m/s and a horizontal velocity of 43.3m/s. It strikes a target above the ground 3.00 seconds later. a) How high is the target above the gound? b) How far did the projectile travel before hitting the target? c) What is the horizontal component of the velocity of the projectile right as it hits the target? d) What is the vertical component of the velocity of the projectile right as it hits the target?
