In skee ball the player rolls a ball with initial speed v0 up a ramp that makes an angle θ with respect to the ground and that, at its end, has height h. as the ball goes up the ramp it slows down with an acceleration of magnitude a. the aim is to put the ball in a bucket, also at height h, but a distance d away from the ramp. find v0 in terms of h, θ, a, d, and the acceleration due to gravity g = 9.8 m/s2 .

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

Idon’t quite understand this problem

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
