Projectile Motion

A passenger on a boat moving at 1.20 m/s on a still lake walks up a flight of stairs at a speed of 0.50 m/s. The stairs are angled at 45° pointing in the direction of motion as shown. What is the velocity of the passenger relative to the water? Find the Magnitude(m/s) & Direction (above the water) ... See attached

Projectile Motion

A swimmer is capable of swimming 0.95 m/s in still water. (a) If she aims her body directly across a 150 m wide river whose current is 0.55 m/s, how far downstream (from a point opposite her starting point) will she land? (m) (b) How long will it take her to reach the other side?(s)

Projectile Motion

Romeo is chucking pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with only a horizontal component of velocity. He is standing at the edge of a rose garden h = 6.7 m below her window and d = 8.0 m from the base of the wall. How fast are the pebbles going when they hit her window?( m/s )... see at ...continues

Projectile motion

A hunter aims directly at a target (on the same level) 100 m away. (a) If the bullet leaves the gun at a speed of 280 m/s, by how much will it miss the target? (b) At what angle should the gun be aimed so the target will be hit?

Projectile Motion

A light plane is headed due south with a speed relative to still air of 280 km/h. After 1 hour, the pilot notices that they have covered only 150 km and their direction is not south but southeast. What is the wind velocity? Find the magnitude (km/h) & angle (° north of east)

The maximum height a projectile will reach.

A projectile is launched with an initial velocity at an angle above the ground. What is the maximum height the projectile will reach? Please see the attached file for full problem description.

The displacement of a hockey puck.

Help to double check my answer. At time t = 0 s a hockey puck is moving with a velocity of 18 m/s. It is decelerating at a rate of 0.95 m/s^2 (squared). What displacement will the puck have in 1.5 s Answer with number of meters round to the nearest whole number. Thanks
