The drawing shows a skateboarder moving at 4.8 m/s along a horizontal section of a track that is slanted upward by 48° above the horizontal at its end, which is 0.54 m above the ground. When she leaves the track, she follows the characteristic path of projectile motion. Ignoring friction and air resistance, find the maximum height H to which she rises above the end of the track.

Two aircraft p and q are flying at the same speed ,300m s^-1, the direction along which p is flying is at right angle to the direction along which q is flying .find the magnitude of the velocity of aircraft p relative to aircraft q.,,,,,,(hellllp if poassible lead to to graph too I have 5 hours to school to submit it
P.s ( are they goin the same direction or opposite I didn't get the right angle to q

If an airplane travels in one direction half of the time at 55km/h ,and the other half at 90km/h.
What is the total distance traveled by the airplane?
It just seems that it does not give you enough information ,but the teacher says there is a way.

I have a review of structure for proposed building. Do you have people to complete

why can't energy be created or destroyed i want to know the reason

In a performance test, each of two cars takes 8.8 s to accelerate from rest to 26 m/s. Car A has a mass of 1442 kg, and car B has a mass of 1863 kg. Find the net average force that acts on (a) car A and (b) car B during the test.

a uniform rod of length 5m and weight 20N us supported at the 1 meter mark and at the 4 meter mark. a painter of weight 750N stands at the 3 meter mark. calculate the reaction at each support

A 22 kg child is on a slide in a playground. She climbs 4.50 m to the top. Determine the velocity that the child would leave the slide if it was frictionless.

a uniform rod of length 5m and weight 20N is supported at the 1m mark and at the 4m mark. A painter of weight 750N stands at the 3m mark. Calculate the reaction at each support.

A car starts from rest on a curve with a radius of 100m and accelerates at 1.0m/s^2 .Through what angle will the car have traveled when the magnitude of its total acceleration is 2.1m/s^2 ?
