I need help on this problem: A cannon tilted upward at θ= 28 fires a cannonball with a speed of 93 m/s. At that instant, what is the component of the cannonball’s velocity parallel to the ground? Express your answer in meters per second.

An airplane on a humanitarian mission is traveling horizontally at 190 m/s at 350 m above the surface of the earth.  The airplane wants to drop a supply package to a refugee camp below and it lands on the camp 8.45 s later. How far away from the refugee camp (horizontally) should the airplane drop its package so that it lands in the refugee camp?

A space vehicle is coasting at a constant velocity of 24.4 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.223 m/s² in the +x direction. After 52.7 s, the pilot shuts off the RCS thruster. After the RCS thruster is turned off, find (a) the magnitude and (b) the direction of the vehicle's velocity relative to the space station. Express the direction as an angle (in degrees) measured from the +y direction. (a) Number i Units (b) Number Units û

The position vector is r = (3t3 - 2t)i + (2t+1)j (above r,i,j has Vector symbol) Determine the velocity vector at t = 2.0s. Your answer should be in m/s.

Could I have help with this physics question?

I want to verify the direction for both the velocity and acceleration vector of the given vector r.

A student standing on a cliff that is a vertical height d = 8.0 m above the level ground throws a stone with velocity v0 = 17 m/s at an angle θ = 27 ° below horizontal. The stone moves without air resistance; use a Cartesian coordinate system with the origin at the stone's initial position.   With what speed, vf in meters per second, does the stone strike the ground?

A cannon tilted upward at θ = 29 ∘ fires a cannonball with a speed of  98 m/s . At that instant, what is the component of the cannonball’s velocity parallel to the ground?

The Moon orbits the Earth in an approximately circular path. The velocity of the moon as a function of time is given by:vx     =     −v sin(?t)vy     =     v cos(?t)where v = 945 m/s and ? = 2.46  10-6 radians/s. What is the average acceleration of the Moon over the following time intervals? For each, give the magnitude and direction as an angle measured counterclockwise from the positive x-axis.(a) from t = 0 to t = 0.200 daysmagnitude ______m/s2direction ______° counterclockwise from the +x-axis (b) from t = 0 to t = 0.0020 daysmagnitude ______m/s2direction ______° counterclockwise from the +x-axis

A space vehicle is coasting at a constant velocity of 20.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.351 m/s2 in the +x direction. After 33.2 s, the pilot shuts off the RCS thruster. After the RCS thruster is turned off, find (a) the magnitude and (b) the direction of the vehicle's velocity relative to the space station. Express the direction as an angle (in degrees) measured from the +y direction.
