What is the magnitude of the truck's velocity relative to the ground?

An arrow is released with an initial velocity of 22 m/s at an angle of 36 degrees above horizontal. Determine the time it takes for the arrow to reach a horizontal range of 45 meters

A man can row a boat in still water at 6km/h. He wishes to row due north across a river 3km wide which is flowing due east at 2km/h a) by drawing,find the resultant velocity of the boat b) find the time taken to reach the other bank

A bullet is fired horizontally with an initial velocity of 800 m/s at a target located 350 m from the rifle. How much time is required for the bullet to reach the target?  The time required for the bullet to reach the target is ___s.

An airplane maintains a speed of 573 km/h relative to the air it is flying through as it makes a trip to a city 766 km away to the north. (Assume north is the positive y-direction and east is the positive x-direction.) (a) What time interval is required for the trip if the plane flies through a headwind blowing at 35.1 km/h toward the south? h(b) What time interval is required if there is a tailwind with the same speed? h(c) What time interval is required if there is a crosswind blowing at 35.1 km/h to the east relative to the ground? h

A  ball is kicked with a velocity at an angle of 30 degrees.  If the ball travels a horizontal distance of 40 m before hitting the ground, determine the initial velocity of the ball.

Which expression correctly gives the total time the projectile spends in the air? t = _______ a) vi/g b) 2vi/g c) vi sin(θ)/g d) 2 vi sin(θ)/g

A person rows a boat 4 m/s directly west across a stream that flows south at 3 m/s. What is the resultant velocity of the boat as it crosses the river?

A ball is launched straight up and then falls straight back down to the ground. Which of the following statements is true about the ball at the peak of it's trajectory?   Question 3 options:   The magnitude of the ball's displacement relative to the ground is zero   The magnitude of the ball's velocity relative to the ground is zero   The magnitude of the ball's acceleration relative to the ground is zero   All of the above   None of the above

How will the velocity change when the acceleration is perpendicular to it? None of the magnitude and direction will change. The magnitude of velocity will change and the direction will not. The direction of velocity will change and the magnitude will not. Both the magnitude and direction will change.
