A boy in a car moving at 10 km/h[N] wants to throw a ball to a girl standing on the right-hand side of the road. He is able tothrow the ball at 20 kin/h. He wants the ban to go straight east, directly to her. (a) Relative to the car, which way should he throw the ball in order to do this?
b) Relative to the ground, how fast will the ball travel to reach her?

Pls explain me in details. I’ll give you brainliest if you give me the first right answer

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
